git clone

After cloning the repository you need to build and drop the JAR from the target generated files into the ${PAYARA_HOME}/glassfish/modules directory of your Payara Server Installation.

You must build from the payara6 branch to get the gRPC module compatible with Payara 6


cd grpc
git checkout payara6
mvn clean install
cd grpc-support/target
cp grpc-support-1.0.0.jar ${PAYARA_HOME}/glassfish/modules

Restart the domain and any running instances to enable the module.
