The Collabnet plugin v. 2.0.8 looks like it is incompatible with the promoted builds plugin v. 876.v99d29788b_36b_

We get the following error when trying to promote a build to the Collabnet Team Forge File Release:
FATAL: 'hudson.model.AbstractBuild hudson.plugins.promoted_builds.Promotion.getTarget()'
java.lang.NoSuchMethodError: 'hudson.model.AbstractBuild hudson.plugins.promoted_builds.Promotion.getTarget()'

Rolling back the promoted builds plugin to v. 3.11 resolved this issue and allowed us to successfully promote our builds.
