But the compiler used is system-dependent. All the source/target bits do is impact what the compiler does, not which compiler is used.
If you specify the fork, compilerVersion, and executable properties as I described below, you can use an alternate javac. You can also use a different compiler (see http://maven.apache.org/plugins/maven-compiler-plugin/non-javac-compilers.html) if you want to go there.
