title: Building Android project with Ant -- cannot find symbol
body: <p>I am attempting to build my android project using ant (it runs fine in eclipse).  I run an error with the following build failed line:</p>
  
  <pre><code>BUILD FAILED
  .../android_sdks/tools/ant/build.xml:680: The following error occurred while executing this line:
  .../android_sdks/tools/ant/build.xml:693: Compile failed; see the compiler error output for details.
  </code></pre>
  
  <p>The above java compilation has plenty of errors, all of which are cannot find symbol errors.  Most of these symbols are variables added to the R file.  And some are classes within the project.  </p>
  
  <p>I set up the build environment using:</p>
  
  <pre><code>android update project --path .
  </code></pre>
  
  <p>My tools and platform_tools are all up-to-date and I'm running on android-7.  I've refreshed the project, ran a clean on the project, and even restarted eclipse.  </p>
  
  <p>I'm fairly new to ant and would appreciate any advice.  </p>
  
  <p>The build failing output (as requested, I apologize for the formatting issues):</p>
  
  <p>MacBook-Pro:[company]_Android$ ant clean debugBuildfile: [android_path]/build.xml</p>
