Working on a project that has both java and groovy classes. The groovy classes utilize serialization extensively for permanence and have a significant number of transient properties to reduce the serialized footprint of the classes. The gmaven-plugin 1.0-rc-3 is producing invalid getter and setter stubs for the transient properties. I have attached one of the Groovy classes and the generated java stub for that class in a gzipped tar file. The errors returned are all similar to: target/generated-sources/groovy-stubs/main/org/oclc/dataload/frequency/SimpleCount.java:[41,29] modifier transient not allowed here Where the generated class contains code like: transient private boolean hasFixupSimpleCountDummy = false; transient public boolean getHasFixupSimpleCountDummy() { throw new InternalError("Stubbed method"); } transient public boolean isHasFixupSimpleCountDummy() { throw new InternalError("Stubbed method"); } } transient public void setHasFixupSimpleCountDummy(boolean value) { throw new InternalError("Stubbed method"); }
