Maven checksum failed

Question

I am working on a project that uses Maven as the build tool. I am using version 2.2.1 of the tool. Recently a coworker mentioned that he couldn\'t build the project because of c

Answer 1

The artifact resolver is (still, even in 3.0.4 apparently) not thread safe:

http://jira.codehaus.org/browse/MNG-4742

try building with:

When I build with this option in 3.0.4 in a project that displays checksum errors (for log4j), all of the checksum errors disappear.

It should apply to 2.2.1 as well.
