Hello, I want to build hyperledger/fabric-javaenv:2.2.0 image for fabric v2.2.0 on arm architecture . I followed the instructions from repository: https://github.com/hyperledger/fabric-chaincode-java and when I run ./gradlew clean build install I have the following error: > Configure project :
2.2.0

The issue is that a prebuilt binary for protoc-gen-grpc-java is NOT available for the Arm architecture ( https://repo.maven.apache.org/maven2/io/grpc/protoc-gen-grpc-java/1.23.0/ ). You will need to build it yourself and install it into the local Maven repo on your build machine. There are instructions available at https://github.com/grpc/grpc-java/tree/master/compiler
