SFTP deploy causes NullPointerException
---------------------------------------
Key: WAGONSSH-22
URL: http://jira.codehaus.org/browse/WAGONSSH-22
Project: wagon-ssh
Type: Bug
Versions: 1.0-alpha-4
Environment: Windows XP, Maven 2 Final
Reporter: K.C. Baltz
I'm new to M2, so this may be user error, but even still, I think a more useful
error message would be appropriate.
I'm trying to deploy my project to an internal Remote Repository using SCP or
SFTP (SCP fails with the "session is down" message, so I'm trying SFTP). I get
the attached trace during my build. I'm not exactly sure what metadata it's
hoping to find.
flexo is the name of the server.
Uploading:
sftp://flexo/export/home/kcbaltz/testM2Repo/com/copart/core/core/1.0-SNAPSHOT/core-1.0-20051028.001955-1.jar
[INFO] Retrieving previous metadata from flexo
