If you're still having trouble with creating a feature file and the Cucumber editor isn't set as the default, follow these steps:

1. Create a feature file.
2. Right-click on the feature file.
3. Select Open With.
4. Choose Other....
5. Select Cucumber Editor from the list of internal editors.
6. Check the box that says Use it for all "*.feature" files.

By enabling this option, Eclipse will automatically use the Cucumber editor by default whenever you create a ".feature" file.
