can not create skeleton plugin

[Lukasz Lukasz]

Hi

I have a problem running atlas-create-jira-plugin as described in:

https://developer.atlassian.com/display/DOCS/Create+a+Plugin+Skeleton

all jars seem to download fine into repository, and the result is:

I've already deleted the repositories and downloaded them again. Tried that with maven 2.0.11., 2.2.1, 3.0.2.

Thanks a lot for the help.

Ok resolved. The problem was with wrong java version. Had two javas installed, and I was using 1.5.

Switching to 1.6 resolved the issue.
