steps:

1. ASSERT: use TP 4.13.AM1 matching Eclipse 2019-06
2. EXEC: import jbosstools-central into workspace

Result:
Eclipse reports a compilation error for org.jboss.tools.maven.core

The project was not built since its build path is incomplete. Cannot find the class file for org.eclipse.jem.util.emf.workbench.ProjectUtilities

Interestingly, things compile fine in maven, no errors.
