All, As we started using Protobuf, it is important to know how you make changes to .proto files and how to compile them. Easiest way: 1. Download protobuf compiler from: http://code.google.com/p/protobuf/downloads/list 2. Install protobuf-dt eclipse plugin as detailed here: http://code.google.com/p/protobuf-dt/ 3. Configure the destination directory to generate the java files as detailed in step 2 here: http://code.google.com/p/protobuf-dt/wiki/IntegrationWithProtoc Set the "Java Output Directory" to: src/main/java 4. VERY IMPORTANT FOR JBPM: jBPM Flow project has a .proto file that extends the data types defined in the .proto file in Drools Core, so you need to configure the protobuf import path as detailed here: http://code.google.com/p/protobuf-dt/wiki/ImportPaths Add the following import paths to the jbpm-flow project: ${your drools-core project in eclipse}/src/main/resources ${your_drools_flow_project}/src/main/resources After doing that, when you edit and save the .proto files, eclipse will automatically compile and regenerate the java source code for them.

Mauricio, Just to clarify, the change from the previous approach to this approach with Protobuf is a low level change that should not affect existing features... I mean, it changes the binary format, but not the higher level APIs/use cases.

is the following correct? When a change does not change a proto file, it is never needed to run the protobuf compiler. So its build impact is similar to antlr. Is the a protobuf maven plugin so the intellij/netbeans/vi people can compile them too? -- View this message in context: http://drools.46999.n3.nabble.com/How-to-work-with-Protobuf-proto-files-t...
