Starting Pixelitor in an IDE

Pixelitor requires Java 21+ to compile. When you start the program from an IDE, use pixelitor.Pixelitor as the main class.

Building the Pixelitor jar file from the command line

1. OpenJDK 21+ has to be installed, and the environment variable JAVA_HOME must point to the OpenJDK installation directory.
2. Install Maven
3. Check the Maven installation with mvn --version
4. Execute mvn clean package in the main directory (where the pom.xml file is), this will create an executable jar in the target subdirectory. If you didn't change anything, or if you only changed translations/icons, then you can skip the tests by running mvn clean package -Dmaven.test.skip=true instead.
