> Try to making a pom for do a reproducible build, meaning by reproducible build the ability to produce the exact same artifact (same checksum) starting from the same code, a two different times, i had some trouble with the files generated in: /META-INF/maven/groupId/artifactId/ 
> in the specific the  /META-INF/maven/groupId/artifactId/pom.properties contains the timestamp.
> digging in the code in the class: http://svn.apache.org/viewvc/maven/shared/tags/maven-archiver-3.0.0/src/main/java/org/apache/maven/archiver/PomPropertiesUtil.java?revision=1708674&view=markup
