I am trying to access an external Java API (IBM Rational Rhapsody Java API) in my generator. For this, I created a new Solution (named RhapsodyApi) which imports the *.jar-File and provides the stubs.
I can access the stubs from my generator, so far I am fine. If I try to use methods from the API which contains e.g. a "String" parameter, it is stated as "no classifier". I found out, that in the RhapsodyApi solution, complex data types like "String" are marked as "Unresolved Reference". I tried to add "java.lang@java_stub" to the "core@java_stub" model but after reopening the options for "core@java_stub", the Dependencies-Tab is again empty.
How can I fix this Reference issue?
I am using JetBrains MPS 3.3.2.
Thanks a lot....
