Why doesn't "Source> Organize Imports" work in Eclipse?

Question

I am writing a Hello World SWT application in Eclipse (following the instructions given by Eclipse). At some point, I need to “Right-click in the Java editor and choose Source> Organize Import.

I did this on Eclipse installed on Ubuntu. This operation generated import statements at the beginning of my code. But that was not enough for my program to work. I needed to add some import statements with my hands, after which my code worked fine.

Now I am trying to do the same in Eclipse installed on Windows. In this case, the situation is even worse. "Source> Organize Imports" does not change anything (it does not add any import statements to the beginning of the code).

Does anyone have any ideas why it is not working properly?

Answer 1

Scenario 1: The package that Eclipse needs to identify may not be in your path to the project path.

Scenario 2: Eclipse cannot resolve your class name, because in different packages there can be two different classes with the same name. In such scenarios, a pop-up dialog box appears asking you to select the appropriate class. The old version of eclipse cannot pop up, leaving you to manually find and resolve.

Answer 2

Your source must be compiled without errors before any of them are applied.
