title: Aptana Studio 3 "Building Workspace" with EXT 4 Library
body: <p>I have a web project setup in Aptana Studio 3. 
  I like the IDE, but so far my biggest issue with it is how long it takes for it to "Build the workspace". It seems to take forever to sort through all of the EXTJS 4.x files. </p>
  
  <p>Everytime I rebuild the theme file, it takes at least 30 minutes, and the whole time the IDE can't be used. Or if I update the EXT version, it has to go through it all again. </p>
  
  <p>I am sure I could remove the EXT files from the tree entirely until I put my code on the server, but I don't like for things to be scattered, and I am likely to forget to put it back. </p>
  
  <p>Is there anyway I can have it exclude the EXTJS files from process it goes through?
  I have try right clicking on the folder in the tree and "Exclude from Index" but that doesn't seem to work at all (This might not even be used for what I think it is). </p>
  
  <p>When I put a whole new set of library files in, this process has taken up to 2 hours. And even if I stop it, it takes 5 or 6 minutes to actually stop. </p>
  
  <p>I realize that the machine I am working on isn't very powerful, but I think this is a little ridiculous, especially for as often as it happens. </p>
  
  <p>Any advice on this other than "get a more powerful machine" would be greatly appreciated. 
  If it helps I am running Kubuntu 11.10 32 bit. </p>
