Hi Angelo,
Codelens is disabled when Eclipse is just started. You need to get the focus on the editor to enable Codelens.
Scenario to reproduce the problem
- Start Eclipse
- Create a Java project with two depending classes (based on the Angelo's example)
- Open Java classes on the editor
- Restart Eclipse
- The Java classes are opened but Codelens is not enabled. You need to get the focus to enable it.
