title: Set Antlr4 custom generation path relative to project root?
body: <p>Using the <a href="https://plugins.jetbrains.com/plugin/7358?pr=" rel="nofollow">Antlr4 intellij plugin</a>.  I want to customise the directory into which Antlr puts generated code.  Right-Clicking the grammar file and selecting <code>Configure Antlr...</code> enables this: <code>Output directory where all output is generated</code>.  However: it's an absolute path.  </p>
  
  <p>That breaks project portability, e.g. can't work on the project across linux &amp; windows machines.</p>
  
  <p><strong>So: is there a way to enter the generation path relative to the module root?</strong></p>
  
  <p>Thanks.</p>
