title: Gradle ERROR: ProductFlavor names cannot start with 'test'
body: <p>Tried to name my productFlavor as "test" and received the error:</p>
  
  <pre><code> ERROR: ProductFlavor names cannot start with 'test'
  </code></pre>
  
  <p>From the source code I see the simple check:</p>
  
  <pre><code> private void addBuildType(BuildType buildType) {
      if (buildType.name.startsWith("test")) {
          throw new RuntimeException("BuildType names cannot start with 'test'")
      }...
  }
  </code></pre>
  
  <p>Appears I can use names like "myTest", "aTest", etc., but not "test1", "test2" etc.
  Any possible reason for this? Thanks.</p>
