title: How do I resolve this error message to create an Enum: "Project 'MyFunProject' is not a J2SE 5.0 compliant project."
body: <p>I am learning about using Enum in a project which will be used within a switch statement. I get this error message when I click >New>Enum from the project folder: "Project 'MyFunProject' is not a J2SE 5.0 compliant project."</p>
  
  <p>My installed JREs (Preferences > Java > Installed JREs) includes JAVA SE 6 and JAVA SE 8, but only JAVA SE 8 is actually selected.  The error message seems to imply that I have some setting somewhere referencing Java SE 5, but I cannot find anything else to corroborate that theory.</p>
