[mojo-dev] PATCH - For capturing exec-maven-plugin output to a file

[M Singh]

Hi:

I was recently working on a project that required capturing exec-maven-plugin 
output to a file that would be packaged in the final maven artifact.  By 
default the current exec-maven-plugin sends the output to the console.

I added the file capturing functionality and am attaching the patch file for 
your review.  Please let me know if you would like to include this in your code 
base.

Thanks.
