Description

It seems that access to local Maven repository is not concurrent-safe that is multiple Mavens running in parallel may damage contents of local Maven repository. It would be a nice improvement, because sharing of local repository will lower the need for contacting any other repository. I know that Maven proxy can be used, but that adds another layer which may unnecessarily stress the machine it runs on.

NOTE: http://takari.io/book/30-team-maven.html#concurrent-safe-local-repository is a Takari Extension for Apache Maven that introduces a concurrent-safe local-repository.
