Why is my Eclipse Java package being treated as a folder?

My Eclipse Java package is treated as a folder; can anyone suggest what’s wrong?

Answer

Worst case, you’ll have to delete the folder and recreate as a java package.

• Save the Java classes somewhere else in your Java project by refactoring
• Delete the folder and the underlying folder structure
• Create a Java package
• Move the Java classes back under the Java package by refactoring
