title: Liferay Portlet do not appear in the menu option for portlet
body: <p>I am following the official Liferay tutorial 7.1,</p>
  
  <p>I have started the server and installed the first "guestbook portlet".
  However, it is not showing in the list of available portlets (the menu which shows when you click on the + button ).</p>
  
  <p>I went back to Eclipse and I can see that my module ( the only one I have ) has an error symbol on it. However, no error message is displayed anywhere.</p>
