gRPC codegen fails for large file name like io.envoyproxy.controlplane:api on windows

[ls-bit]

Describe the bug

I stumbled upon this problem while testing envoy control plane api.

gRPC codegen fails with an exception when adding quarkus.generate-code.grpc.scan-for-proto=io.envoyproxy.controlplane:api to scan envoy controlplane api for proto files.

Caused by: io.quarkus.bootstrap.prebuild.CodeGenException: Failed to generate java files from proto file in C:\test\code-with-quarkus\build\classes\java\quarkus-generated-sources\proto\.

Probably only an issue on windows, as it builds fine on a WSL Ubuntu VM.

Note that the io.envoyproxy.controlplane:api artifact also contains generated code, so it is possible to use the code from the artifact.

Expected behavior

No exception occurs

Actual behavior

java.io.IOException: CreateProcess error=206, The filename or extension is too long occurs

I'm not sure we can do anything. Can you try with WSL?

[ls-bit]

Yes, it works with WSL. Maybe it is possible to pass some kind of parameter file to protoc as mentioned in protocolbuffers/protobuf#274 ?

[cescoffier]

Hum, it worse a try - I fear it's windows specific (meaning I cannot test).

[ls-bit]

if it is of any help, i can offer to test on windows

[cescoffier]

@ls-bit Sorry for the late reply - can you check #39291?

[ls-bit]

Awesome, I can confirm that the issue is fixed by your PR, thanks!

[cescoffier]

Thanks for the feedback!
