Re: [m2e-users] Dependencies with classifiers not working

[Fred Bricon <fbricon@xxxxxxxxx>]

Hi,

I reproduced the bug with m2e-wtp, this explains why it impacts STS. 

It thinks, wrongly, there's a duplicate dependency and tries to be clever (and utterly fails) in moving one of them in the target folder.

I opened https://issues.sonatype.org/browse/MECLIPSEWTP-192 to keep track of this issue.

I'll try to fix it this week-end so you can try a dev build ASAP.

Regards,

Fred Bricon

I would be surprised if this problem has anything to do with STS, but
you never know and it would be good to try to reproduce the problem in
a vanilla Eclipse install.  FWIW, I tried to naively reproduce
jacquie's bug using this simple pom file, but could not.

It would be very helpful if you could send over a failing project.

Here's the pom that I used.  It correctly found the dependencies in
the .m2 directory.  Could there be something else going on with your
configuration causing maven to look for dependencies in odd places?
