title: Gradle not working inside container but does outside
body: <p>For some reason gradle is not working for me from w/in a docker container.  Of course, outside the container it works fine.  What's strange is that it doesn't say what file or directory is missing.</p>
  <pre><code># ./gradlew clean -s
