Description

Some of the time, deploying artifacts fails during the scp transfer. The bottom of the stack trace is reproduced below. If I run the m2 deploy enough times, it succeeds; not sure why.

This is not an unknown issue with Jsch; apparently client code can cause behavior like this if it doesn't dispose of connections properly. Possibly a plugin that's runs before the deploy phase is messing up the connection state somehow?
