title: Default eclipse working directory
body: <p>Is it possible to set a default working directory in Eclipse 3.4.1? By Default that is:</p>
  
  <p>${workspace_loc:(project name)}</p>
  
  <p>But I want it to be something like</p>
  
  <p>${custom_var}</p>
  
  <p>Per class, I can change the Run configuration -> arguments -> Working directory to "Other", but it's better if the default can be changed. I have a lot of classes that needs to be run from that particular directory.</p>
