Eclipse IDE - Open Call Hierarchy is empty/broken

Question

What should I do, if the \"Open Call Hierarchy\" is broken (empty for every method in a project)? It only shows the name of the method I wanted to see the call hierarchy fo

Answer 1

If the call Hierarchy is not opening, it might be because of the project is not imported as a java project, rather it would be displayed in the file stucture. You may want to enable the project facet through:

right click on the project -> project facet.  

If you dont see anything listed, you need

configure the project facet -> Apply -> ok.
