Status: Closed (View Workflow)
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$DirectedSpecifics.getEdgeContainer(Unknown Source) at org.jgrapht.graph.AbstractBaseGraph$DirectedSpecifics.outDegreeOf(Unknown Source) at org.jgrapht.graph.AbstractBaseGraph.outDegreeOf(Unknown Source) at se.diabol.jenkins.pipeline.domain.Stage.findAllRunnablePaths(Stage.java:267) at se.diabol.jenkins.pipeline.domain.Stage.placeStages(Stage.java:225) at se.diabol.jenkins.pipeline.domain.Stage.extractStages(Stage.java:164) at se.diabol.jenkins.pipeline.domain.Pipeline.extractPipeline(Pipeline.java:123) at se.diabol.jenkins.pipeline.DeliveryPipelineView.getComponent(DeliveryPipelineView.java:323) 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.
