1.2. Manual build

The manual build require JDK >= 17 and Maven >=3.6. Then run:

mvn package

This command create a new directory in the parent directory of the plugin called app (relative path: ../app/). In the app directory there is a directory called plugins, in which there is a directory for the plugin. This is the compiled plugin. You can copy this directory in your GroIMP plugin directory (or in /home/.grogra.de-platform/plugins) and start GroIMP.
