Migrate from Eclipse to IntelliJ IDEA

Switching from Eclipse to IntelliJ Idea, specially if you lot've been using Eclipse for a long time, requires understanding some primal differences between the two IDEs, including their user interfaces, compilation methods, shortcuts, projection configuration and other aspects.

Import an Eclipse project to IntelliJ Idea

You can import either an Eclipse workspace or a unmarried Eclipse project. To practice this, click Open up on the Welcome Screen or select in the main menu.

IntelliJ IDEA automatically detects Eclipse projects located on your calculator and places them in the dedicated node right on the Welcome screen. This node will be available among the recent projects until you make up one's mind to remove it. When the Eclipse projection is in the node, just click it to chop-chop open it in the IDE.

If your project uses a build tool such as Maven or Gradle, nosotros recommend selecting the associated build file pom.xml or build.gradle when importing the project. For more than information on how to import a project, refer to Import a project from Eclipse.

If you'd similar to import your existing run configurations from Eclipse, consider using this third-political party plugin.

User Interface

No workspace

The commencement thing you'll notice when launching IntelliJ IDEA is that it has no workspace concept. This means that you can work with only one project at a fourth dimension. While in Eclipse yous normally have a fix of projects that may depend on each other, in IntelliJ IDEA yous accept a single project that consists of a gear up of modules.

If you accept several unrelated projects, you can open them in separate windows.

If you however want to accept several unrelated projects opened in i window, as a workaround yous can configure them as modules.

IntelliJ IDEA vs Eclipse terminology

The table beneath compares the terms in Eclipse and IntelliJ Idea:

Eclipse	IntelliJ IDEA
Workspace	Project
Project	Module
Facet	Facet
Library	Library
JRE	SDK
Classpath variable	Path variable

No perspectives

The second big surprise when you switch to IntelliJ Thought is that it has no perspectives.

It ways that you don't demand to switch between unlike workspace layouts manually to perform unlike tasks. The IDE follows your context and brings upward the relevant tools automatically.

Tool windows

Just like in Eclipse, in IntelliJ IDEA you lot likewise have tool windows. To open a tool window, click it in the tool window bar:

If the tool window bar is subconscious, you can open any tool window past hovering over the corresponding icon in the bottom left corner:

If y'all want to make the tool window bar visible for a moment, you tin can printing Alt twice and hold it.

If yous don't want to use the mouse, you tin can ever switch to any toolbar past pressing the shortcut assigned to it. The most of import shortcuts to think are:

• Project: Alt+one

• Commit: Alt+ix

• Terminal: Alt+F12

Some other thing near tool windows is that yous can drag, pin, unpin, attach and detach them:

To assist store/restore the tool windows layout, there are two useful commands:

• (too available via Shift+F12)

Multiple windows

Windows management in IntelliJ Thought is slightly different from Eclipse. You can't open up several windows with 1 project, but yous can detach whatever number of editor tabs into dissever windows.

Always select opened files

By default, IntelliJ Idea doesn't change the selection in the Project tool window when you switch between editor tabs. However, yous can enable information technology in the tool window settings:

General workflows

No 'save' push

IntelliJ IDEA has no Salvage button. Since in IntelliJ IDEA you can undo refactorings and revert changes from Local History, it makes no sense to ask you to save your changes every time.

All the same, information technology's worth knowing that physical saving to disk is triggered by certain events, including compilation, closing a file, switching focus out of the IDE, and and then on. Y'all can change this behavior via :

Save deportment

If you are an experienced Eclipse user, you are familiar with save actions: the actions triggered automatically on save, such as reformatting code, organizing imports, and so on.

IntelliJ Idea also features salve deportment that you tin discover and enable in .

On top of that, IntelliJ Idea offers you to run the corresponding deportment automatically on commit:

Or manually:

• Ctrl+Alt+L

• Ctrl+Alt+O

Compilation

The way IntelliJ Idea compiles projects is different from Eclipse in a number of ways.

Auto-compilation

Past default, IntelliJ IDEA doesn't automatically compile projects on saving considering unremarkably we don't invoke the save action explicitly in IntelliJ Thought.

If you desire to mimic the Eclipse behavior, you can invoke the Build Project activity Ctrl+F9 - it will salve the changed files and compile them.

You can too enable the Build projection save action in .

Annotation that automated compilation in IntelliJ IDEA differs from that in Eclipse. In Eclipse it's not fully automated, equally it is triggered by the save activeness invoked by the user explicitly, whereas in IntelliJ IDEA it is invoked implicitly when y'all type in the editor.

This is why, even if the Build project pick is enabled, IntelliJ IDEA doesn't perform automated compilation if at least one awarding is running: it will reload classes in the application implicitly. In this example you can call Ctrl+F9.

Problems tool window

The Bug tool window appears if the Build project option is enabled in save deportment. Information technology shows a list of problems that were detected on project compilation.

Eclipse compiler

While Eclipse uses its ain compiler, IntelliJ IDEA uses the javac compiler bundled with the project JDK. If you must use the Eclipse compiler, navigate to and select it as shown below:

The biggest difference between the Eclipse and javac compilers is that the Eclipse compiler is more than tolerant to errors, and sometimes lets you run lawmaking that doesn't compile.

In situations when you demand to run code with compilation errors in IntelliJ IDEA, replace the Build option in your run configuration with Build, no mistake check:

Shortcuts

IntelliJ IDEA shortcuts are completely different from those in Eclipse.

The table below shows how the superlative Eclipse actions (and their shortcuts) are mapped to IntelliJ IDEA (you may want to print it out to e'er take it handy).

Eclipse	IntelliJ Idea

Eclipse keymap

For Eclipse users who prefer not to learn new shortcuts, IntelliJ Thought provides the Eclipse keymap which closely mimics its shortcuts:

Detect action

When you don't know the shortcut for some action, try using the Notice action feature bachelor via Ctrl+Shift+A. Start typing to notice an activity by its name, see its shortcut, or phone call information technology:

Coding assistance

Both Eclipse and IntelliJ IDEA provide coding assistance features, such as code completion, code generation, quick-fixes, live templates, so on.

Quick-fixes

To apply a quick-ready in IntelliJ IDEA, press Alt+Enter:

All quick-fixes are based on inspections configured in :

If you lot want to apply a quick-fix to several places at one time (that is to a whole folder, module or even a project), you lot tin exercise it by running the corresponding inspection via or by running the whole batch of inspections via :

Apart from outright problems, IntelliJ Idea as well recognizes code constructs that tin can be improved or optimized via the so-called intentions (also available with Alt+Enter):

Eclipse	IntelliJ Idea
Action	Shortcut	Action	Shortcut
Quick fix	Ctrl+ane	Show intention activity	Alt+Enter

Generating lawmaking

The key action for generating code is , available via Alt+Insert:

This action is context-sensitive and is available not only within the editor, simply also in the Projection tool window and the Navigation bar:

Code completion

IntelliJ Thought provides several different types of code completion, which include:

• Basic completion

• 2d bones completion

• Type-matching completion

• Second type-matching completion

• Statement completion

To learn more about the differences between these completion types, refer to the Code Completion weblog mail service.

By default, IntelliJ IDEA doesn't show the Documentation popup for the selected item, merely you can enable information technology in :

If you lot don't want to enable this pick, you can manually invoke this popup by pressing Ctrl+Q when you need it:

When the caret is within the brackets of a method or a constructor, you can get the info about the parameters past calling Parameter Info with Ctrl+P:

Eclipse	IntelliJ Thought
Action	Shortcut	Activeness	Shortcut
Code completion	Ctrl+Infinite	Basic completion	Ctrl+Space
-	-	Type-matching completion	Ctrl+Shift+Infinite
-	-	Argument completion	Ctrl+Shift+Enter

Templates

You may be used to typing main in the editor and then calling code completion to take it transformed into a principal method definition. However, IntelliJ Idea templates are a little different:

Template	Eclipse	IntelliJ IDEA
Define a chief method	chief	psvm
Iterate over an array	for	itar
Iterate over a collection	for	itco
Iterate over a listing	for	itli
Iterate over an iterable using foreach syntax	foreach	iter
Print to System.out	sysout	sout
Print to Arrangement.err	syserr	serr
Define a static field	static_final	psf

The list of available templates can exist found in . At that place you can also add your ain templates or alter any existing ones.

Postfix templates

In addition to 'regular' templates, IntelliJ IDEA offers the so-called postfix templates. They are useful when yous want to use a template to an expression you lot've already typed. For example, type a variable proper noun, add together .ifn and press Tab. IntelliJ Thought will plow your expression into a if (...==aught){...} statement.

To see a complete list of available postfix templates, go to .

Surround with live template

The surround with templates is another addition that works similarly to alive templates but can be applied to the selected code with Ctrl+Alt+J.

To ascertain your own surround with template, go to and use $SELECTION$ within the template text:

$LOCK$.readLock().lock(); endeavor { $Pick$ } finally { $LOCK$.readLock().unlock(); }

Refactorings

The following table maps the shortcuts for the most common refactorings in Eclipse with those in IntelliJ IDEA:

Eclipse	IntelliJ Thought
Activity	Shortcut	Activity	Shortcut
Extract local variable	Ctrl+Alt+Fifty	Extract variable	Ctrl+Alt+V
Assign to field	Ctrl+2	Extract field	Ctrl+Alt+F
Testify refactor quick menu	Alt+Shift+T	Refactor this	Ctrl+Alt+Shift+T
Rename	Ctrl+Alt+R	Rename	Shift+F6

To larn more about many additional refactorings that IntelliJ IDEA offers, refer to Top 20 Refactoring Features in IntelliJ IDEA

Undo

Sometimes, refactorings may affect a lot of files in a project. IntelliJ IDEA not simply takes care of applying changes safely, merely also lets y'all revert them. To undo the last refactoring, switch the focus to the Project tool window and press Ctrl+Z.

Search

Beneath is a map of the most common search deportment and shortcuts:

Eclipse	IntelliJ IDEA
Activity	Shortcut	Activeness	Shortcut
Open search dialog	Ctrl+H	Observe in Files	Ctrl+Shift+F
References in workspace	Ctrl+Shift+G	Find usages	Alt+F7
-	-	Show usages	Ctrl+Alt+F7
-	-	Find usages settings	Ctrl+Alt+Shift+F7
Occurrences in file	Alt+Ctrl+U	Highlight usages in file	Ctrl+F7

Navigation

The table beneath roughly maps the navigation actions available in Eclipse with those in IntelliJ Idea:

Eclipse	IntelliJ IDEA
Action	Shortcut	Action	Shortcut
Quick access	Ctrl+3	Search everywhere	Double Shift
Open blazon	Ctrl+Shift+T	Navigate to course	Ctrl+N
Open resource	Ctrl+Shift+R	Navigate to file	Ctrl+Shift+N
-	-	Navigate to symbol	Ctrl+Alt+Shift+N
Quick switch editor	Ctrl+E	Switcher	Ctrl+Tab
-	-	Recent files	Ctrl+Eastward
Open declaration	F3	Navigate to proclamation	Ctrl+B
Open up blazon hierarchy	F4	Navigate to type hierarchy	Ctrl+H
-	-	Bear witness UML popup	Ctrl+Alt+U
Quick outline	Ctrl+O	File structure	Ctrl+F12
Dorsum	Ctrl+[	Dorsum	Ctrl+Alt+Left
Forrad	Ctrl+]	Forrad	Ctrl+Alt+Right

Afterwards, when yous become used to these navigation options and need more than, refer to Top 5 Navigation Keyboard Shortcuts in IntelliJ Thought Shortcuts.

Call hierarchy

Both IntelliJ Thought and Eclipse provide features that allow you to examine the hierarchy and explore the structure of source files. For example, the Telephone call Hierarchy characteristic shows you all the callers and callees of the selected method.

In Eclipse, you admission information technology past pressing Ctrl+Alt+H . In IntelliJ Thought, use the Ctrl+Alt+H shortcut.

Autonomously from telephone call hierarchies, IntelliJ Idea can likewise build method hierarchies (Ctrl+Shift+H) and type hierarchies (Ctrl+H). You can find more information in Source code bureaucracy.

Lawmaking formatting

IntelliJ IDEA code formatting rules (bachelor via ) are similar to those in Eclipse, with some minor differences. You may want to take note of the fact that the Apply tab character choice is disabled past default, the Indent size may be unlike, etc.

If yous would like to import your Eclipse formatter settings, go to , click , click Import Scheme and select the exported Eclipse formatter settings (an XML file).

Notation that there may be some discrepancies between the lawmaking style settings in IntelliJ Thought and Eclipse. For example, you cannot tell IntelliJ Thought to put space afterward (just not before). If you lot want IntelliJ IDEA to use the Eclipse formatter, consider installing the Eclipse code formatter plugin.

Eclipse	IntelliJ Thought
Action	Shortcut	Action	Shortcut
Format	Ctrl+Shift+F	Reformat code	Ctrl+Alt+L

Run and reload changes

Similarly to Eclipse, IntelliJ IDEA likewise has Run/debug configurations dialog that y'all can access either from the master toolbar, or the principal menu. Compare the related shortcuts:

Eclipse	IntelliJ IDEA
Action	Shortcut	Action	Shortcut
Run	Ctrl+Shift+F11	Run	Shift+F10
Debug	Ctrl+F11	Debug	Shift+F9
-	-	Make	Ctrl+F9
-	-	Update application	Ctrl+F10

Equally mentioned earlier, past default IntelliJ Idea doesn't compile changed files automatically (unless yous configure it to do so). That ways the IDE doesn't reload changes automatically. To reload changed classes, call the Build action explicitly via Ctrl+F9. If your application is running on a server, in addition to reloading you can use the Update awarding action via Ctrl+F10:

Debug

The debuggers in Eclipse and IntelliJ Thought are similar only use different shortcuts:

Eclipse	IntelliJ Idea
Activity	Shortcut	Action	Shortcut
Stride into	F5	Step into	F7
-	-	Smart stride into	Shift+F7
Step over	F6	Step over	F8
Step out	F7	Step out	Shift+F8
Resume	F8	Resume	F9
Toggle breakpoint	Ctrl+Shift+B	Toggle breakpoint	Ctrl+F8
Evaluate expression	Ctrl+Shift+I	Evaluate expression	Alt+F8

Application servers

Deploying to awarding servers in IntelliJ IDEA is more or less similar to what you lot are probably used to in Eclipse.

Deploy your application to a server

1. Configure your artifacts via Projection Structure | Artifacts (done automatically for Maven and Gradle projects).

2. Configure an application server via Settings/Preferences | Application Servers.

3. Create a run configuration and then specify the artifacts to deploy and the server to deploy to.

For more information, come across Application servers.

Build and rebuild your artifacts via .

IntelliJ IDEA doesn't provide visual forms for editing Maven and Gradle configuration files. Once you've imported or created your Maven or Gradle project, you can edit its pom.xml or build.gradle files directly in the editor. After, you can synchronize the project model with the changed files on demand, or automatically import changes to the new build files. Whatsoever changes to the underlying build configuration will somewhen need to be synced with the project model in IntelliJ IDEA.

For operations specific to Maven or Gradle, IntelliJ Idea provides the Maven Project tool window and the Gradle tool window. Apart from your project structure, these tool windows provide a list of goals or tasks plus a toolbar with the relevant deportment.

For transmission synchronization, employ the corresponding action on the Maven or Gradle tool window toolbar: .

Run goals/tasks

Use the Maven or Gradle tool window to run whatever project goal or task. When you exercise, IntelliJ IDEA creates the respective run configuration, which y'all tin can reuse later to run the goal or job quickly.

It'due south worth mentioning that any goal or task tin exist fastened to a run configuration. This may be useful when your goal or job generates specific files needed by the application.

Both the Maven and Gradle tool windows provide the Run Task action. It runs a Maven or Gradle command similarly to how you'd run it using the console.

Configure artifacts

If you take a WAR artifacts configured in your pom.xml or build.gradle file, IntelliJ IDEA automatically configures the corresponding artifacts in .

Annotation that when y'all compile your projection or build an artifact, IntelliJ Idea uses its own build process which may be faster only is non guaranteed to be 100% accurate. If you observe inconsistent results when compiling your projection with Build in IntelliJ IDEA, try using a Maven goal or a Gradle task instead.

Version command systems

IntelliJ IDEA supports Git, Mercurial, Subversion, Perforce and other version command systems (VCS).

Configure VCS roots

When you lot open a project located under a VCS root, IntelliJ Thought automatically detects information technology and suggests adding this root to the project settings.

• To change version control-related projection settings (or manually add a VCS root), go to Settings/Preferences | Version Command.

  

IntelliJ IDEA works perfectly with multi-repository projects. Just map your project directories to VCS, and the IDE will take care of the remainder. For Git and Mercurial, the IDE will fifty-fifty offer you synchronized branch command, so that y'all tin perform co-operative operations on multiple repositories simultaneously. For more information, see Manage Git branches.

Edit VCS settings

Every VCS may crave specific settings, for case, Path to Git executable, GitHub/Perforce credentials, and and so on:

One time you've configured the VCS settings, yous'll run across the Version Command tool window Alt+9.

Checking projects out

To cheque out a projection from a VCS, click Become from Version Command on the Welcome Screen, or in the main VCS bill of fare.

Working with local changes

The Local Changes view shows your local changes: both staged and unstaged. To simplify managing changes, all changes are organized into changelists. Any changes made to source files are automatically included into the active changelist. Y'all can create new changelists, delete the existing ones (except for the Changes one), and move files between changelists.

Correct-click the unversioned file or binder you lot want to ignore in the Local Changes tab of the Version Command tool window Alt+9 or in Project tool window and select or .

If you want ignored files to be also displayed in the Local Changes view, click on the toolbar and select Show Ignored Files.

Working with history

The Log tab of the Git tool window lets you lot come across and search through the history of commits. You can sort and filter commits by the repository, branch, user, date, folder, or even a phrase in the clarification. You can find a item commit, or simply browse through the history and the branch tree:

Working with branches

IntelliJ Thought lets yous create, switch, merge, compare and delete branches. For these operations, either use Branches from the main or context VCS carte, or the VCS operations popup (you can invoke it by pressing Alt+`, or the widget on the right of the status bar:

All VCS operations are available from the VCS main menu:

Action	Shortcut
Version Command tool window	Alt+9
VCS operations popup	Alt+`
Commit changes	Ctrl+K
Update project	Ctrl+T
Push button commits	Ctrl+Shift+Grand
