The Original Java generator fails with error "No classes or packages produced from the transformation. Nothing is generated." The following error can be found in console : -------------- Compilation errors found in unit 'platform:/plugin/org.eclipse.papyrus.designer.languages.java.generator.transfo.umltojdt/transforms/uml/uml2jdt2.qvto' Cannot find imported compilation unit 'Strings' (at:18) -------------
The error come from the /org.eclipse.papyrus.designer.languages.java.generator.transfo.umltojdt/transforms/uml/uml2jdt2.qvto file. The import of the String compilation unit should be removed.
Removing the " import String; " solves the bug. The generator works again and generate code correctly. However, an exception is thrown in the console : !ENTRY org.eclipse.ocl 4 10 2016-04-30 01:37:02.635 !MESSAGE ERROR in (calloperation): (null) !STACK 0 java.lang.NullPointerException at
