java.long.NoClassDefFoundError when Job DSL not installed

Issue Type:	Bug

Reporter:	Brian Krische

I do not have the Job DSL plugin installed. It seems that because I don't, the promoted builds plugin logs the following stack trace at Jenkins startup.

Job DSL is listed as an optional dependency, so it should probably do a better job of checking if it exists when loading instead of dumping a nasty stack strace to the Jenkins log.
