Build KOMMA with Maven

KOMMA is a plain Maven project. You can simply use mvn package to compile and package all modules or mvn install to install them within your local Maven repository.

If you like to build an Eclipse update site (or rather a P2 repository) for KOMMA then use

mvn package -Pupdatesite

to create it. Afterwards a P2 repository can be found at features/net.enilink.komma.updatesite/target/repository.

Develop KOMMA with an IDE

  • Eclipse: You can import the KOMMA projects into your workspace by executing File > Import > Maven > Existing Maven Projects.

  • IntelliJ IDEA: You can import the KOMMA projects by executing File > New > Project from Existing Sources…​.
