OSGi Services are usually first created by declaring a java service interface class. As an OSGi service, this interface class serves as both the name for the service in the service registry, and defines the service contract (i.e. the interface method signatures...i.e. the method name, argument types, and return types) for that version of the service.
gRPC (Google RPC) is a popular and high-performance rpc approach that allows developers to define networked services based upon protocol buffers (proto3).
By extending bndtools recently-added code generation capability, it's now possible to generate an OSGi (remote) service API from just a proto3 service declaration. All the classes necessary for an OSGi Remote Service API (service interface, arg and return types) can be generated by bndtools within Eclipse from a single proto3 file, immediately and completely.
Ready to implement-and-consume OSGi Services can be generated by Eclipse+bndtools + a proto3 service declaration.
Further, the proto3 service declaration can be modified, and the tooling will immediately generate new service API classes, compile, and package them into a bundle, all from within Eclipse+bndtools.
To get this bndtools-grpc generation with an example see here.

Nice example of how to use the source code generation in bnd. It is so wonderful never have to press 'build'! Everything you change anwwhere in the IDE is always up to date.
