SNAPSHOT: Crosss-project compilation error in .generated/org/jboss/errai/bus/client/framework/RpcProxyLoaderImpl.java

Hi,

Building our project today with the most recent SNAPSHOT produces the following error:-

Our project structure has not changed and the referenced classes are not in the project being compiled:-

guvnorng-core

---> Failed compilation

guvnorn-showcase (depends on guvnorng-core)

src/main/java/org/drools/guvnor/shared/AssetService

src/main/java/org/drools/guvnor/shared/vo/asset/AbstractAsset

Please advise.

Thanks,

Mike

Hi Michael,

During the compilation of guvnorng-core, Errai found an @Remote interface that has a dependecy to these types. Can you check in RpcProxyLoaderImpl to see which interface that is? Errai should only find @Remote interfaces that are in the specified gwt client/source packages of the module under compilation or its inherited modules.

Thanks,

Christian

Thanks Christian.

The project that fails to compile does not contain any interfaces annotated with @Remote that reference the classes reported in the error.

Johnathan said he could not replicate with a fresh clone of our project from github. Deleting and cloning again on my PC resolved the problem so a duff cached file somewhere.

With kind regards,

Mike
