Description

Maven will automatically download dependencies to the local repo. With multimodule parallel builds it's possible for different modules to request the download of the same dependency causing a concurrent unsynchronized access to the local .m2 repo.
One thread might be writing the .part file and moving it to it's final position while the other is still trying to access the .part file.
