> Several users of m2e-wtp complained invoking *mvn package* (without clean) on their project generates a jar containing duplicate pom.properties and pom.xml.

> This is caused by m2eclipse-mavenarchiver generating these files during eclipse incremental builds, under target/classes.
> The proper course of action is generally to invoke mvn clean package, in that case, but I believe the archiver should never generate zips with duplicate entries in the first place.
> I don't have an opinion whether the mavenarchiver generated files should take precedence over the existing ones, or the other way around. Whatever solution is chosen, a warning should be logged in case of duplicates.
