Hello everyone,
I was trying to use grpc(1.4.0) in karaf(4.1.1), but failed.
Following are my steps:
1) wrote the grpc "HelloWorld" demo, and built it as an osgi bundle.
2) wrote a feature.xml file which use to install dependencies, such as
io.netty.*, io.grpc.*, and built the feature
3) start karaf and install the feature
main code of features.xml
<feature name="rgpc-demo-feature" description="grpc demo feature"
