But that would introduce > a potential mismatch between protoc and protobuff JAR. > Still If you want to use different version of protoc/protobuff from the one > defined in the POM, you can use the -Dprotobuf.version=#### to specify your > alternate version. But I would recommend not to do this, because if you > publish the artifacts to a Maven repo, the fact you used > -Dprotobuf.version=#### will be lost and the version defined in the POM > properties will be used (IMO Maven should use the effective POM on deploy, > but they don't). -- This message is automatically generated by JIRA.
