title: Ant : warning: 'includeantruntime' was not set
body: <p>Ok, I'm building an android project with ant. 
  I have built the project hundreds of times without an issue, but all of a sudden Ant is playing up, and I have no idea why (I haven't updated it in the last half hour that I have been building my project.)</p>
  
  <p>It seems to be this javac statement: </p>
  
  <pre><code>&lt;javac srcdir="./" classpath="../external-deps/OUYA/ouya-sdk.jar" /&gt;
  </code></pre>
  
  <p>When I remove it, it builds fine. </p>
  
  <p>The error I'm getting is :</p>
  
  <pre><code>warning: 'includeantruntime' was not set defaulting to build.sysclasspath=last; set to false for repeatable builds
  </code></pre>
  
  <p>I have however set the includeantruntime value to false, and true , however when I do so it seems like ant is ignoring my Android libraries by throwing out this error constantly:</p>
  
  <pre><code>error: package android.content does not exist
  error: package android.hardware.input does not exist
  error: package android.util does not exist
  etc.
  </code></pre>
  
  <p>So, I have no clue what's going on. Again, I haven't changed any configuration at all, it just sprung up on me.</p>
  
  <p>I'm on a 32bit Ubuntu 13 machine.
  I have been playing with git, but I have checked all my files from a non git backup, and the files are identical.</p>
  
  <p>Thanks for your time.</p>
  
  <p>Here is my build.xml : <a href="http://pastebin.com/H5019R6E" rel="nofollow">http://pastebin.com/H5019R6E</a></p>
