title: Seemingly random numbers in Eclipse project files
body: <p>Looking at Eclipse <code>.cproject</code> and <code>.project</code> files I see many seemingly random numbers: </p>
  
  <pre><code>&lt;targetPlatform id="cdt.managedbuild.target.gnu.platform.mingw.exe.debug.928002373"
  &lt;tool id="cdt.managedbuild.tool.gnu.assembler.mingw.exe.debug.1473978281"
  &lt;inputType id="cdt.managedbuild.tool.gnu.assembler.input.1028037841" 
  &lt;tool id="cdt.managedbuild.tool.gnu.archiver.mingw.base.917558104"
   etc...
  </code></pre>
  
  <p>What are the numbers for? </p>
  
  <p>I am writing a script that generates the files, and I am unsure if I need to change those numbers for each project I generate the files for - or they can stay the same? </p>
  
  <p>Projects may be open in same workspace, so I am affraid of some kind of collisions. </p>
