If I want to change the UML code generator, what is the best way to
proceed? I have several projects in my workspace (org.eclipse.uml2.uml,
org.eclipse.uml2.codegen.ecore, org.eclipse.uml2.codegen.ecore.ui) and I
do not know which one to change if I want to add some additional code to
e.g. all getters of some specific UML element. Also, how can I re-run the
code generator then?
