IDE Setup Instructions

Before you start contributing, please follow the instructions below to setup a code style for an IDE of your choice.

Open the Preferences window, and then navigate to Java → Code Style → Formatter. Click Import and then select the build/optaplanner-ide-config/src/main/resources/eclipse-format.xml file in the ide-configuration directory.

Next navigate to Java → Code Style → Organize Imports. Click Import and select the build/optaplanner-ide-config/src/main/resources/eclipse.importorder file.

Open the Preferences window (or Settings depending on your edition), navigate to Plugins and install the Eclipse Code Formatter Plugin from the Marketplace.

Restart your IDE, open the Preferences (or Settings) window again and navigate to Other Settings → Eclipse Code Formatter.

Select Use the Eclipse Code Formatter, then change the Eclipse Java Formatter Config File to point to the eclipse-format.xml file in the build/optaplanner-ide-config/src/main/resources/ directory. Make sure the Optimize Imports box is ticked, and select the eclipse.importorder file as the import order config file.
