The Pipeline type in Jenkins 2.19.x is not supported by the TFS Plugin. This is a new type introduced in the workflow plugin and the current TFS Plugin does not have a dependency on it, hence it fails on Pipelines.

Line 206 of TeamBuildEndpoint.java attempts to retrieve an AbstractProject by name. If it is a pipeline, null is returned, resulting in an IllegalArgumentException("Project not found");.

Can the TFS Plugin take a dependency on a later version of Jenkins that supports pipelines?
