title: How can I open non-Netbeans Java project using Netbeans?
body: <p>I'm using Netbeans for my Java development, and every time I download a project that has been developed using other IDE, I can't run the project because of errors.</p>
  
  <p>Is there any way to open regular people's projects easily without headache.
  Note : the project am trying to open is not an Eclipse project, so I can't use the Eclipse importer.</p>
  
  <p>And usually what are Java developers using for development?</p>
