Running compile from within another mojo

[Magne Rasmussen <Ma...@invenia.no>]

Hi.
 
I have an plugin which processes the class files generated by compile,
generates a new java file based on the class files, and then needs to
compile this generated java file.
 
The question is: Can I get hold of, and run, the compile mojo from
within my plugin? If so, how do I do that?

Hi,

I've been looking at doing something similar. I want to call another
MOJO  from within my MOJO.

There is entry in the mailing archives. See
(http://mail-archives.apache.org/mod_mbox/maven-dev/200511.mbox/%3Cc38ad92d0511161552k24920759s2ed19b2d807a20f5@mail.gmail.com%3E)

A suggestion is made to run a plugin by invoking maven again through a
command line interface. (This is how it is done in the
maven-release-plugin)

So then you could:
1) Invoke your MOJO
2) Use the command line to run compile
3) Do your stuff
3) User the command line to run compile again

Cheers,
Ian

No, you can't.
You should split this up into 2 projects - one that produces the first class files,
and a second project that generates code from the class files of the first project.

There might be a workaround though, but it's not recommended: process the classes
in the process-classes phase, generating the source files.

Then configure the compiler plugin to also run in the process-classes phase to compile
the newly generated sources. It might not run in the correct order, though.
I really recommend splitting up into 2 projects.
