title: Android: ANT build fails with google-play-services-lib: "resolve to a path with no project.properties file for project"
body: <p>I'm trying to build my apps using ANT and I'm failing miserably after I included the google-play-services-lib library project. </p>
  
  <p><strong>Step 1</strong></p>
  
  <p>I set up a reference to the library project in my project.properties file:</p>
  
  <pre><code>android.library.reference.1=/path/to/google-play-services_lib
  </code></pre>
  
  <p><strong>Step 2</strong></p>
  
  <p>I ran these commands inside the google-play-services_lib folder:</p>
  
  <pre><code>android update lib-project --path .
  ant clean
  ant release
  </code></pre>
  
  <p>BUILD SUCCESS!</p>
  
  <p><strong>Step 3</strong></p>
  
  <p>Back to my project folder</p>
  
  <pre><code>ant clean
  ant release
  </code></pre>
  
  <p><strong>ERROR</strong></p>
  
  <pre><code>BUILD FAILED
  /android/tools/ant/build.xml:460: /path/to/google-play-services_lib resolve to a path with no project.properties file for project /my/project-folder
  </code></pre>
  
  <p>There IS a project.properties in both folders, naturally. The one in google-play-services_lib contains this code:</p>
  
  <pre><code>target=android-8
  android.library=true
  </code></pre>
  
  <p>I'm obviously missing something that's right there in front of me and I'd really appreciate your help. Thanks!</p>
