To reproduce, I've just downloaded the STS, then created a new maven project, then run install on the project. In the jar file that is produced in
(test is the name for the project), I get two pom.properties, and two pom.xml.
The two pom.properties have these lines at the top:
#Generated by Maven Integration for Eclipse
#Thu Dec 22 08:22:50 NZDT 2011
#Generated by Maven
#Thu Dec 22 08:23:05 NZDT 2011
So looks like there are two passes giving two sets of files?
I've also pulled down Indigo, and done the same there - which seems to work fine, hence I'm logging it here.
Hope you can provide a way forward for this - the duplicate files cause other parts of the build to break.
