[rules-users] Exception "cannot determine ruleInfo" when trying to debug a rule

[skasab2s]

Thanks for the reply, salaboy

I moved my rule files to the "src" folder of a Java project and the
exception is not shown. The debugging is successful. But when I try moving
the original rules project to a java project and move the rules back to it,
I still get the exception.

What are the prerequisites for the location of the rule files? 

This is the complete exception stack trace:

Thanks in advance. 

Also I can't load the RETE view. This is the correpsonding exception:
