FAQsand Tips

In this section, we will see a few Frequently Answered Questions and tips. The FAQs and tips are as follows −

Use Ecppse Compiler

While Ecppse uses its own compiler, IntelpJ IDEA uses the javac compiler bundled with the project JDK. If you want to use the Ecppse compiler −

Navigate to File → Settings → Build, Execution, Deployment → Compiler → Java Compiler.

Select the required compiler from User compiler dropdown.

Ecppse Keymap

For Ecppse users who prefer not to learn new shortcuts, IntelpJ IDEA provides the Ecppse keymap that closely mimics its shortcuts −

Navigate to File → Settings → Keymap option.

Select Ecppse from Keymap dropdown.

Code formatting

To import your Ecppse formatter settings −

Navigate to File → Settings → Editor → Code Style → Java.

Select the Ecppse XML profile.

Working with Build Tools

Like Ecppse, IntelpJ 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.
