AbortCompilation: Pb(324) - class cannot be resolved, indirectly referenced #195

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Unclear when this happens, but sometime I get the following stacktrace.
Apart from the stacktrace I see nothing going wrong.

I've had seen this from time to time, too. Maybe a problem with type inference, 
where the return type of method should be defined explicitly or there is a 
dependent library missing on the classpath, I will have a look at it.

The problem seems to start from the JDT,  which needs to find the xbase 
compiler. It seems we need to put the xbase compiler in the MANIFEST of the 
JDT. That is very much outside our scope.

GoogleCodeExporter commented 9 years ago 
have not seen this exception for a long time, so I close this issue. If it 
occurs again, this issue should be reopened.
