title: Eclipse Git | Reverting merge commit
body: <p>Using Eclipse Git (the one bundled by default on Eclipse Mars.1 - JavaEE version), is it still possible to remove/delete a wrong merge commit?</p>
  
  <p>Since I'm still new to the UI of Eclipse Git coming from a terminal user, I accidentally merge the wrong branch <code>dev-release</code> to a <code>dev-master</code>. Which should have been the other way around. Luckily I haven't pushed yet that merge commit to remote.</p>
  
  <p>My question is, is it possible to undo the merge commit using Eclipse Git only?</p>
