[Tobago] apt-plugin JDK tools.jar dependency

[Evan Worley <ev...@gmail.com>]

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?)

Hi Wendy,

I think it would make a lot of sense because annotation processing is hardly
related to JSFs and was probably only created as a supporting technology.
Who can work on pulling this out to the Codehaus Mojo project?

Thanks,
Evan

Struts 2 is also using this plugin... if it's not JSF-specific, does
it make sense to take it over to the Codehaus Mojo project where it
would be easier to collaborate on?

Brett pointed out that there is another apt plugin over there in the
sandbox;  I'm not sure if they're related.
