title: calling gradle "build" task in another project
body: <p>I am only a couple of days into using gradle</p>
  
  <p>In my current build.gradle script I have a task which I would like to call the build task in another project (ie. defined in a different build.gradle somewhere else) after each time it is executed</p>
  
  <p>My question is how do I call a task from another project?</p>
  
  <p>I guess I want to do something like tasks.build.execute() but it doesn't seem to work. I tried this:</p>
  
  <pre><code>commandLine "${rootDir}\\gradle", 'build', 'eclipse'
  </code></pre>
  
  <p>it at least executed the build and eclipse for my current project just not the master project. Hope my question is clear</p>
