Hello.
I am trying to generate a KDM code model programmatically. For this purpose, i use the following instructions:
IProject project = ResourcesPlugin.getWorkspace().getRoot().getProject(projectName);
IJavaProject javaProject = JavaCore.create(project);
DiscoverKDMModelFromJavaProject kdmDiscoverer = new DiscoverKDMModelFromJavaProject();
kdmDiscoverer.discoverElement(javaProject, new NullProgressMonitor());
Resource kdmResource = kdmDiscoverer.getTargetModel();
//serialize
However, i get a NullPointerException with the method discoverElement() and i don't exactly know what is going wrong with this code. Could you help me figure it out? Is there a better way to to generate a KDM code model programmatically? Here are the details of the NullPointerException i get:
java.lang.NullPointerException
