I installed the java libraries using `mvn install` in protobuf-2.3.0/ java, but still get the same errors when trying to do `make java` in protobuf-2.3.0/examples. I've never used Maven before - is there something I need to set up so javac knows where to look to find the jarfile maven created (~/.m2/repository/com/google/protobuf/protobuf- java/2.3.0/protobuf-java-2.3.0.jar)?
I've tried % export CLASSPATH=~/.m2/repository % make java and % export CLASSPATH=~/.m2/repository/com/google/protobuf/protobuf-java/ 2.3.0/ % make java But both seem to give the same error.
