[m2t-dev] Acceleo Builder not supporting projects in subdirectories

[Didier Villevalois <dvillevalois@xxxxxxxxxxxxx>]

Hello list,

We are willing to use Acceleo for a project that is in a subdirectory of
our workspace (in a Maven module to be more precise).

We are getting a null pointer exception (stack trace follows).
The problem seems to be in the AcceleoProject.getOutputFilePath(...)
method which tries to compare the source file's absolute full path
(for instance /testproject/innerproject/src/main/java/generate.mtl)
to the source folders of the project (/innerproject/src/main/java/)
without any success.

The getFullPath() call must be replaced by a getProjectRelativePath()
call. The patch follows. We would be glad if you could include that for
the next release. (Or maybe we could have it in a nightly build ?)

Thanks for Acceleo. Keep up the great work.
Sincerely, Didier Villevalois.
