Brian Jackson updated MRELEASE-310:
-----------------------------------

    Attachment: ForkedMavenExecutor.patch

Attached patch with test case.  The patch uses the maven.home system property 
to find the mvn executable.  I now understand that the original process can't 
spawn children with a different maven version since the mvn script checks that 
the M2_HOME environment variable is set and matches the version running.

> ForkedMavenExecutor assumes mvn is on command-line path

> The ForkedMavenExecutor assumes the mvn executable is on the command-line 
> path.  This will cause the release goals to fail if mvn is run from an 
> explicit path and the PATH environment variable has not be set to contain a 
> mvn executable.  More dangerously though is the case where the release goal 
> is started with an explicit mvn executable of one version (for instance 
> 2.0.8) but a different version of the mvn executable is available on the 
> PATH.  The forked processes will run a different version of Maven2 that the 
> parent process.
