This is a "known" limitation. I note that this is not mentioned in the 
README, but should.

Basically we can only debug the _first_ test action (e.g. @compile or 
@run). If a test contains multiple actions, the debugger session 
attaches to the first, and then we get a failure (like you did). For 
now, the only workaround is to manually "comment" out the tags that are 
not required, so that only one test action remains.

I do not have enough knowledge of IntelliJ internals (e.g. debugging 
API) to understand how to redirect the debugger from one process to 
another; if others do, we'd be more than happy to fix this long standing 
issue.
