[GitHub] [beam] kennknowles opened a new issue, #18256: Improve error message for missing required Pipeline options in Datalflow runner for Java SDK

[GitBox <gi...@apache.org>]

kennknowles opened a new issue, #18256:
URL: https://github.com/apache/beam/issues/18256

   Here is an example error message when we fail to set GCP project ID:
   
   Caused by: java.lang.IllegalArgumentException: Missing required value for [public abstract java.lang.String org.apache.beam.runners.dataflow.options.DataflowPipelineOptions.getProject(), "Project id. Required when running a Dataflow in the cloud. See https://cloud.google.com/storage/docs/projects for further details."](public abstract java.lang.String org.apache.beam.runners.dataflow.options.DataflowPipelineOptions.getProject(), "Project id. Required when running a Dataflow in the cloud. See https://cloud.google.com/storage/docs/projects for further details.").
   
   We should make the error message more actionable by suggesting a command line parameter that sets the pipeline option or pointing to relevant programmatic API that sets it.
   
   Full error message:
