Dan Armbrust commented on MINSTALL-54:
--------------------------------------
I have run across this, in researching this issue - will be testing it out
myself:
[http://takari.io/book/30-team-maven.html#concurrent-safe-local-repository]
No idea why this code has to be outside of core maven:
[https://github.com/takari/takari-local-repository]
rather than just being merged into maven, to fix the problem for everyone....

> Looks like there might be an issue with updates to

> maybe a solution is to add {{maven-metadata-local.xml.lock}} to ensure two
