Fix wrong toolchains label in Custom Plugins document #318

Closed Ginakira closed 1 month ago

Ginakira commented 2 months ago

Version: v4.6.0 In custom plugin, if I defined toolchain attribute as @rules_proto_grpc//protoc:toolchain_type in proto compile rule just same as document:

# Create compile rule
example_compile = rule(
    implementation = proto_compile_impl,
    attrs = dict(
       ...
    ),
    toolchains = [str(Label("@rules_proto_grpc//protoc:toolchain_type"))],
)

It has error when build:

(11:16:43) ERROR: /.../BUILD:29:20: While resolving toolchains for target //foo_protoc:foo_proto: com.google.devtools.build.lib.packages.BuildFileNotFoundException: no such package '@rules_proto_grpc//protoc': BUILD file not found in directory 'protoc' of external repository @rules_proto_grpc. Add a BUILD file to a directory to mark it as a package.

Replace it to @rules_proto_grpc//protobuf:toolchain_type will resolve this problem. And I found there is no folder named protoc under the <bazel_cache_dir>/external/rules_proto_grpc.

Maybe code of the document is outdated. Please review this pull request, thanks!

Thanks, but you are looking at the docs for the v5 release but using the v4 release. The docs for the version you are using are at https://rules-proto-grpc.com/en/4.5.0/custom_plugins.html (4.6.0 is not being shown by RTD for some reason)

Sorry, I didn't notice that. Thanks for your reply! :)
