Here’s a gist with a subset of the build log [1]. When it works fine, it’s copying a jar, when it’s not, it’s copying an empty folder.

However, this is not only happening for the org.infinispan.server.rest module, others show the same issue [2]. What seems to be a pattern is that it only happens with modules that are built by us, it’s not happening for modules coming with the base AS/WF instance.

I’ve traced back and this might be due to build failures that are not producing the right jars [3].

@Stuart, this is really our problem. Sorry for the inconvenience!
