Want something like "failonerror" for artifactspublisher

Is there any way to get CC to consider the build failed if the 
artifactspublisher fails? It's logging an error about not being able to copy 
the file in question, but CC still says the build was successful.

(I have some build-type tasks that are not causing the build to fail when they 
fail, despite failOnError="true", and it seems one of the simplest ways to 
catch all of them is to report a failure when the artifact doesn't exist.)
