Make problems with remote deployment explicit

The deployment to a remote repository might lead to some server-side problem - in my case, the utilized SFTP account did not had enough permissions in the repository path. It would be good if the info message:

— snip —

[INFO] Error deploying artifact: Error occured while deploying 'j2ee/j2ee/1.4/j2
ee-1.4.jar' to remote repository: sftp://maven.asg-platform.org/opt/maven/maven2
/repository

— snip —

could say something more about the original problem. The stack trace (maven -e) knows the answer, at the very end:
