eclipse java import organizing

in test classes I have the following import ``` import static org.junit.Assert.*; ``` when I do organize import via ctrl + shift + o then it automatically changes to following ``` import static org.junit.Assert.assertEquals; import static org.junit.Assert.assertFalse; import static org.junit.Assert.assertNotNull; import static org.junit.Assert.assertTrue; ``` How can I configure eclipse not to do it ? PS: I only want junit imports not be handled in that way ============= I added a save action to remove unused imports. [properties -> java editor -> save actions] so everytime I save unused imports are removed (since I used ctrl + shift + o mainly to remove unused imports this looks like a way forward..)
