Hello all,
Below is a thread that originated on the maven developers list. It seems
that the maven-apt-plugin could use some more infrastructure around
resolving the dependency on the JDK's tools.jar. Here is the original
thread, any thoughts would be great.
Thanks,
Evan Worley

I think you can use ${java.home}/../lib/tools.jar (and remember to
omit it on non-Sun JVM platforms), and document that the user must be
running Java from the JDK, not a JRE (and present a helpful error
message if the class you are looking for cannot be found). You might
look at the source for plexus-compiler-javac for some guidance. I'm
not sure if that is all in the scope of what you are doing or
something the apt plugin should be doing (aren't there other
implementations of the apt plugin too?)
