title: Where to add compiler options like -ea in IntelliJ IDEA?
body: <p>I want to add the <code>-ea</code> option. I set it in <code>Project Settings</code> --> <code>Compiler</code> --> <code>Java Compiler</code> : <code>Additional command line parameters</code>.  </p>
  
  <p>But it caused a make error: <code>invalid flag: -ea</code>.
  P.S.: the above error message may not be the same as yours, because IntelliJ showed error in my native language, not English. I translated it into English.</p>
