Hi,
we use mvn on both local developer's machines as well as some central CI
servers and machines reserved to do the "real" release builds. This means
different OS, Nexus instances used as proxy and so on.
When we encounter the "it works on my machine", it takes us some time to spot
the differences which might be the cause for this. It seems that the class
org.apache.maven.execution.MavenSession contains many of the interesting
parameters, but I have not found a way to "dump" its status so we could compare
it with another MavenSession instance from another machine.
I did some reverse engineering, which does the job for us, but it is - well,
just reverse engineering. Especially the filtering is really depending on the
non-API internals of the classes. Is there a nicer solution available from the
Maven core?
Thanks and kind regards
Andreas
