Hello all,
After failing to customize the compiler pluging (by passing
<compileSourceRoots /> in the maven-compiler-plugin <configuration />); I've
went onto trying to extend the maven-compiler-plugin CompileMojo to just set
that variable.
It looks like I've missed something: the injected parameters of the super
classes are not being set (e.g. the parameter compilerId, or the component
compilerManager in AbstractCompilerMojo are null).
Is there a flag that enables injection of parameters in super classes? Or is
the issue something else?
Thanks :-)
Walid.
Note: a component definition maps the custom-compile goal to the <compile />
phase.
