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).
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <compilerId>eclipse</compilerId> <source>1.5</source> <target>1.5</target> <optimize>true</optimize> </configuration> <dependencies> <dependency> <groupId>org.codehaus.plexus</groupId> <artifactId>plexus-compiler-eclipse</artifactId> <version>1.8.1</version> <scope>runtime</scope> </dependency> </dependencies> </plugin>
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.
