2.1-SNAPSHOT: ErraiMarshalling initialisation RTE

manstis Jul 12, 2012 12:49 PM

Hi,

I don't know if my setup is material, but I'll mention it:-

I have two projects A and B, both use Errai for CDI.

Project A contains "core" stuff, Project B is dependent on Project A for the core stuff.

Both Project A and Project B use Java Annotation Processing to generate some source files (that themselves contain CDI annotations).

Our multi-project POM compiles A and B without problem however at runtime we receive the below trace (I include it all so as not to miss anything that might be of interest).

The problem appears to be when we try to run in an IDE (I use Eclipse, Rikkola - see below - uses InteliJ) with both Project A and B in the workspace.

1) If I have Project B reference Project A and Project A's generated-sources folder is not in the build path I get a GWT exception (source code for projecta.aclass.etc not found. Did you forget to inherit a required module)

2) If I have Project B reference Project A and Project A's generated-sources folder is in the build path I get the stack trace below.

3) If I have Project B reference Project A JAR (i.e. delete Project A from the workspace), delete .errai folder and re-compile it's OK.

4) If I delete the .errai folder, build from CLI (mven clean install) and run with mvn gwt:run it's also OK.

It was first noticed here - https://gist.github.com/3089843 - and after rebasing our project myself today notice the same

Any pointers?

Cheers,

Mike
