[incquery-dev] IncQuery API break (PSystem?) vs IncQuery Maven Compiler

["David, Istvan" <davidi@xxxxxxxxxxxxxx>]

Hi guys,

We encountered an issue with the latest VIATRA build in the CEP module's core plugin, which uses the IQ Maven Compiler. I'm 99% sure it's some IncQuery versioning issue.

It's related to the PSystem (I guess) and it only affects the generated *QuerySpecification classes. Details below.

Typical errors:
[ERROR] import org.eclipse.incquery.runtime.emf.types.EClassTransitiveInstancesKey
[ERROR] import org.eclipse.incquery.runtime.emf.types.EStructuralFeatureInstancesKey;

...
[ERROR] new TypeConstraint(body, new FlatTuple(var_transition), new EClassTransitiveInstancesKey((EClass)getClassifierLiteral("automaton.meta", "TypedTransition")));

The latest line's counterpart in my working copy:

new TypeUnary(body, var_transition, getClassifierLiteral("automaton.meta", "TypedTransition"), "automaton.meta/TypedTransition");

Could you give us a hint please? Thanks!

Cheers,

Istvan
