NPE when using jobs with the same name in different folders

ExportXMLWordPrintable

      When using the same basic item name for more than one job in different folders, and those items are used in a pipeline, the view is not displayed (Error communicating to server! Server Error)

      The stacktrace shows an NPE:

      Caused by: java.lang.NullPointerException
	at org.jgrapht.graph.AbstractGraph.assertVertexExist(Unknown Source)
	at org.jgrapht.graph.AbstractBaseGraph$DirectedSpecifics.getEdgeContainer(Unknown Source)

	at se.diabol.jenkins.pipeline.DeliveryPipelineView.getPipelines(DeliveryPipelineView.java:293)
	... 90 more

      The reason is that ProjectUtil.getAllDownstreamProjects() stores the projects in a map using the simple name as a key. So of all equally named projects only one is retained, so the firstProject is usually not found as vertex in the graph leading to the NPE.

      I will create a Pull Request for that.
