<div><br></div><div> All,</div><div><br></div><div> Today protobuf used by Drools/jBPM was upgrade to version 2.5.0. If you only use the marshalling code, you don't need to do anything. Maven should automatically download the new version and use it.</div>
<div><br></div><div> If you do protobuf development and need to re-generate the protobuf classes from time to time, here is a reminder of how to configure your environment. Please note that the configuration of the plugin (specially for the jBPM module) is extremely important, or you will start to have all kinds of errors and will not know why.</div>
