Eclipse: An internal error occurred during: “Updat

Question

I'm following the instructions for creating data flow java project here When I trying to edit the run configuration as described in the instruction I get the following alert:

An internal error occurred during: "Update Hierarchy".
Tried to create a TypeHierarchyPipelineOptionsHierarchy for a Java Project bq-gettingstarted where no PipelineOptions type exists

I continued following the instructions ignoring the above but then I get:

An internal error occurred during: "Launching BigQueryJavaGettingStarted (1)".
Tried to create a TypeHierarchyPipelineOptionsHierarchy for a Java Project bq-gettingstarted where no PipelineOptions type exists

Any solution?

Answer 1

That error occurs when the PipelineOptions type is not present within the classpath of the Eclipse Project. This signifies that the Dataflow PipelineOptions class is not on the classpath for your Eclipse project.

If the com.google.cloud.dataflow:google-cloud-dataflow-java-sdk-all is in the POM, and the project compiles, the maven dependencies may not have been properly resolved. From the project context menu, select the Maven -> Update Project item, check the "Force Update of Snapshots/Releases" checkbox, and run the update. This should ensure the Dataflow Jar is on the classpath, which will enable the Dataflow Eclipse Plugin to resolve the base PipelineOptions class, and the remainder of the PipelineOptions class hierarchy.
