Annotation processor does not handle well incremental compilation ----------------------------------------------------------------- Key: IPROTO-96 URL: https://issues.jboss.org/browse/IPROTO-96 Project: Infinispan ProtoStream Issue Type: Bug Affects Versions: 4.3.0.Alpha6 Reporter: Nistor Adrian Assignee: Nistor Adrian Priority: Major Fix For: 4.3.0.Alpha7 The RoundEnvironment might not always contain the whole root elements from source path. In case of incremental compilation that will certainly be an issue, preventing discovery of @ProtoXyz annotated classes. A possible way to solve this is to annotate the generated code with that list of user classes from which it originates. This allows us to trace back to the classes that need to be scanned by which are not present in RoundEnvironment as root elements.
