Additional context

Hi team,
We tried to build and test the protoc-gen-grpc-java binary on ppc64le using the following commands, and were successful:

curl -LO https://github.com/grpc/grpc-java/archive/refs/tags/v1.47.0.tar.gz
tar xzf v1.47.0.tar.gz
cd grpc-java-1.47.0/compiler
../gradlew java_pluginExecutable -PskipAndroid=true
../gradlew test  -PskipAndroid=true

We noticed that it doesnt exist here:
https://repo.maven.apache.org/maven2/io/grpc/protoc-gen-grpc-java/1.47.0/

Is it possible to include it in the maven repo in 1.47.0 or a subsequent release? Thank you.

We don't have PPC machines and don't test on it. compiler/build.gradle was already updated to compile on the platform (a while back, in #2325), which allowed you to build from source without further changes.

We don't directly support ppcle, but would be willing to accept a community contribution for the platform using cross-compilation. It'd be similar to #6441, but easier because some of those changes were for general-purpose cross-compilation and not tied to aarch64. Looks like the debian package for ppc cross-compilation is g++-10-powerpc64-linux-gnu.
