Today’s blog will guide you through configuring IntelliJ IDEA to efficiently work with Activiti and ensure your development environment is primed for success.

Step-by-Step Configuration Guide

• Set Language Level to 21

  To ensure your code fails fast when using newer Java features, follow this:

  1. Open menu File and select Project Structure.
  2. Click on Modules, navigate to the Sources tab, and ensure the Language level is set to 21.
• Resource Patterns Adjustment

  To prevent changes from being ignored in the next run/debug session:

  1. Open menu File then select Settings (or Preferences… if on a Mac).
  2. Click on Compiler and modify the Resource patterns text field to !?*.java.
• Avoiding StackOverflowError

  To avoid running into StackOverflowErrors during builds:

  1. Go to Settings or Preferences… (Mac).
  2. Click Compiler, then Java Compiler.
  3. In Additional command line parameters, add: -J-Xss1024k.
• Using Google Java Style Guide

  Incorporate a standardized code style for consistency:

  1. Download the IntelliJ code style XML from Google Java Style Guide.
  2. In Settings, navigate to Code Style and import the XML.
  3. Ensure that GoogleStyle is the active scheme.
• Correct File Encodings and Indentation

  Set file encoding to ensure compatibility:

  1. In Settings, locate Code Style under General, and set the Line separator to Unix.
  2. Ensure Global Encoding is set to UTF-8.
  3. Configure tab size, indent, and continuation indent options as follows:
     • Java: Tabs off, Tab size: 4, Indent: 4, Continuation indent: 8
     • XML: Tabs off, Tab size: 2, Indent: 2, Continuation indent: 4
• File Header and License Header Customization

  You’ll want to have an appropriate file header:

  1. In File templates, under the File Header, remove the line @author Your Name.
  2. Import the correct Copyright profile and select Alfresco_Software.xml.

Troubleshooting

• Issue: Code Not Formatting Automatically

  Solution: IntelliJ IDEA does not format code automatically. Use the keyboard shortcut Ctrl + Alt + L to format your code when necessary.

• Issue: Changes to Resources Not Recognized

  Solution: Ensure you have set the correct resource patterns to !?*.java as described in the configuration section.
