Is there any way to automatically remove all unused imports (signaled with a warning) of a project with Eclipse IDE?
Certainly in Eclipse indigo, a yellow line appears under unused imports. If you hover over that, there will be multiple links; one of which will say "Remove unused import". Click that.
If you have multiple unused imports, just hover over one and there will be a link that allows you to remove all unused imports at once. I can't remember the exact wording off hand, but all the links that appear are pretty self explanatory.
press Ctrl+Shift+O and it will remove unwanted imports
Use ALT + CTRL + O. It will organize all the imports. You can find various other options in the "Code" Menu.
EDIT: Sorry it is CTRL + SHIFT + O
Not to reorganize imports (not to unfold .* and not to reorder lines) to have least VCS changeset
you can use custom eclipse clenup as this answer suggests
