            A list of JVM-based `protoc` plugins to invoke when generating Scala code from protobuf files.










44



            The format for each plugin specifier is `NAME=ARTIFACT` where NAME is the name of the










45



            plugin and ARTIFACT is either the address of a `jvm_artifact` target or the colon-separated

            For example, to invoke the fs2-grpc protoc plugin, the following option would work:

            `--scalapb-jvm-plugins=fs2=org.typelevel:fs2-grpc-codegen_2.12:2.3.1`.










50



            (Note: you would also need to set `--scalapb-runtime-dependencies` appropriately










51



            to include the applicable runtime libraries for your chosen protoc plugins.)
