If you want to do this on whole project then inside project –>select src folder–>press Ctrl+Shift+O
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
Better way is just to add “save action” so when you save the project it will clear the unused imports and format the code as well if you like .
Go to Window > Preferences > Java > Editor > Save Actions
and pick what ever you want .
press Ctrl+Shift+O and it will remove unwanted imports
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 cant remember the exact wording off hand, but all the links that appear are pretty self explanatory.
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

Eclipse IDE gives the warning “The import XXX is never used” whenever it detects an unused import in a Java source file and shows a yellow underline. Though the unused import in a Java file does not create any harm, its unnecessary to increase the length and size of a Java source file, and if you have too many unused imports in your Java source file, those yellow underlines and Eclipse warnings affect the readability of your code. In my last post on Eclipse, we looked at some Java debugging tips on Eclipse. In this post, we will see an Eclipse shortcut to remove all unused imports in Eclipse. There are many options to tackle this problem, e.g. you can collapse the import section of code in Eclipse or you can altogether remove all unused imports from Java file, and well see them in this short tutorial.
If you are completely new to Eclipse IDE, then I suggest you to first go through a comprehensive course, like The Eclipse Guided Tour: Part 1 and 2 from Pluralsight, which will teach you everything you need to know about Eclipse from the Java development point of view.
Anyway, lets see how to remove all unused imports from a Java file in Eclipse IDE.
