Using the JDT compiler in normal Maven builds

The Maven Compiler Plugin can be customized to use a different compiler than Javac. One of the options listed for the compilerId setting is “eclipse“. To use it you will have to add a dependency to the plexus-compiler-eclipse (current version: 1.8.1).


A pitfall here is that the compiler compliance level is not automatically set through the target setting. You have to set also optimize=true. Otherwise Java 1.5 sources won’t compile.

The plexus-compiler-eclipse (version 1.8.1) takes a rather old version of JDT, 3.3.0-v_771. To use another version you will have to deploy a newer version of JDT yourself into your repository and list this dependency before plexus-compiler-eclipse.
