Hi,
our JDO build is now reproducible, I just have to follow the
instructions given by hboutemy.
First I call 'mvn clean install' which builds all the artifacts and
stores them in the local maven repository.
Then I call 'mvn clean package artifact:compare' which build the
artifacts again, but only in the target directory.
The plugin compare the artifacts in the maven repository with the ones
in the target directory by creating buildinfos for the artifacts and
comparing them.
This process also works for SNAPSHOT versions.
Regards Michael
