title: How to disable building a project in Eclipse?
body: <p>Is there some way to keep a project open in eclipse without building it?</p>
  
  <p>I have a few projects in eclipse that don't build because of errors. I just want to use them as reference while I edit and build my main project, however I can't run my main because eclipse complains about all the errors from the other projects (my project does not depend on them)</p>
