runDiscoGen fails with NPE #155

Closed DFrenkel closed 2 years ago

DFrenkel commented 4 years ago

Environment details

Steps to reproduce

  1. You want to generate code samples for Cloud Billing (pick any service in scope) for the purpose of uploading them to be used by the Google Cloud Docs website, so you cd toolkit and run 
    ./gradlew runDiscoGen "-Pclargs=--discovery_doc=../discoveries/cloudbilling.v1.json,--gapic_yaml=./src/main/resources/com/google/api/codegen/py/python_gapic.yaml,--output=/tmp/docs/billing/"

Expected

Code samples for Cloud Billing are produced in /tmp/docs/billing and can be reviewed and uploaded

Actual

> Task :runDiscoGen
the generator class 'com.google.api.codegen.gapic.MainGapicProviderFactory' does not extend the expected class 'com.google.api.codegen.discovery.DiscoveryProviderFactory'Exception in thread "main" java.lang.NullPointerException

We're no longer supporting automatic generation of samples from Discovery files. Samples for such API Client Libraries must now be modified or added manually. Samples for the newer Google Cloud Client Libraries (GAPICs) are a different topic. I can provide more info internally.
