The B.proto needs to be packaged into a jar file and listed as a dependency in your project. In that case the maven-protoc-plugin will do as stated in the documentation:
The Plugin automatically scans all project dependencies for bundled .proto > files, and configures proto_path of the Protocol Buffer Compiler to use > those files as imports. ref: http://sergei-ivanov.github.io/maven-protoc-plugin/ So if you start with a maven module with one file, and the appropriate pom.xml with maven-protoc-plugin configured src/main/proto/B.proto it will produce 'B.jar' which you can reference as a dependency from A's pom.xml details: http://sergei-ivanov.github.io/maven-protoc-plugin/usage.html Regards, Paul Nyheim On Wednesday, May 15, 2013 12:30:16 PM UTC+2, Safi Ali wrote: > > Hi, > > I am using maven-protoc-plugin version 0.3.1 to compile my protoc > definations.
