--------------------------------------------
Summary: Download fails if file is currently in use under windows
Key: MRESOLVER-372
URL: https://issues.apache.org/jira/browse/MRESOLVER-372
Project: Maven Resolver
Issue Type: Bug
Reporter: Christoph Läubrich
With the new file-locking in maven-resolver there is a problem under windows if
the file is currently used by another process (this can for example happen in
an IDE ...) and resolver likes to move the file:
{code:java}

My suggestion would be that resolver simply uses the temp file if it can't be
moved to final location and marks it as delete on exit. Even though this is not
optimal, it at least ensures the the build does not fail to the cost that next
time the file needs to be downloaded again.
