In master we use protobuf-maven-plugin to run protoc. The plugin will download protoc binary from the maven repo so you do not need to install protoc on your machine manually.
So you can just install pb 2.5 on your machine. For the general question that how to have 2 protobuf versions on one machine, I think you need to build protoc from source and install it manually, and use symbol link to select the prefered version before you run mvn command.
