Martin Todorov commented on MNG-4142:
-------------------------------------
I have replied to numerous posts on Stack Overflow concerning this particular
issue. People keep hitting this and are unhappy with the current behavior. In
the company I work for, we had to make Jenkins use private repositories for
each project which would be removed before every build, just for the sake of
sanity and for us not losing our minds when a build fails due to this reason.
The problem here is also observed under Maven 3. Furthermore, it's not a
classifier problem. It happens to whatever dependencies you have to modules
which you've installed locally.
My suggestion would be to make the -U option "unlock" the Maven metadata files
so that they are fetched from the remote repository.
I would also appreciate some response from the you guys. What's the problem
here that keeps this issue unscheduled for future releases? We haven't received
an official comment for a long while. :-|

> Is there some who can try if it can reproduce the error with my testcase ?
> It should be easy to create a real IT for maven with it if it is necessary.
