How can I format an entire source tree in Eclipse 3.4 (Ganymede)?

Question

The obvious thing to do would be to:

1. Right-click on the folder that you wish to format.
2. Source > Format

Expected results:
- All java code in the directory and subdirectories are formatted (using the project specific formatting settings)

Actual results:
- None of the java is formatted.

While we're at it, how can we do a batch clean up operation in Eclipse?
From editor, I Right-click > Source > Clean Up, but I can only do one file at a time.

Answer 1

As mentioned in this thread, this (format all jaava source files within a folder) should work since eclipse3.0.

Do you see some kind of error message in the "errors view" ?

Answer 2

I did exactly as you suggested you would like to do, and it did exactly what you suggested was expected. I selected Source | Format for a directory in my src tree and it reformatted all the units within.

EDIT: ...with 3.4.1 Ganymede.

Answer 3

If your code isn't checked out from source control or isn't writable, doing a group operation like this won't check them out or make them writable.

Answer 4

I faced the same issue. I had to switch to packaged Explorer to use the formatter. Under Navigator it does not work. Hope this help.
