NullPointerException when trying to build (publishing to artifactory not enabled)

A simple project that is only set to retrieve artifacts from artifactory (not publish them) failed to build.

Builds that have all artifactory features turned off are fine as are the ones that publish to Artifactory using the "Deploy artifacts to artifactory" post build action. Removing the post build action while still using some of the artifactory plugin functionality causes the following error.

The workaround is not to use Artifactory plugin.

ERROR: Processing failed due to a bug in the code. Please report this to jenkinsci-users@googlegroups.com
