FAQsand Tips
In this section, we will see a few Frequently Answered Questions and tips. The FAQs and tips are as follows −
Use Eclipse Compiler
While Eclipse uses its own compiler, IntelliJ IDEA uses the javac compiler bundled with the project JDK. If you want to use the Eclipse compiler −
- Navigate to File → Settings → Build, Execution, Deployment → Compiler → Java Compiler.
- Select the required compiler from User compiler dropdown.
Eclipse Keymap
For Eclipse users who prefer not to learn new shortcuts, IntelliJ IDEA provides the Eclipse keymap that closely mimics its shortcuts −
- Navigate to File → Settings → Keymap option.
- Select Eclipse from Keymap dropdown.
Code formatting
To import your Eclipse formatter settings −
- Navigate to File → Settings → Editor → Code Style → Java.
- Select the Eclipse XML profile.
Working with Build Tools
Like Eclipse, IntelliJ does not provide visual forms for editing Maven/Gradle configuration files.
Once you have imported/created your Maven/Gradle project, you are free to edit its pom.xml/build.gradle files directly in the text editor.
