title: Docker for Windows exits with code 127 when building image
body: <p>When I try to build this Docker-Image, I get the following error:</p>
  
  <p><img src="https://i.stack.imgur.com/n82qL.png" alt="Log"></p>
  
  <pre><code>FROM java:8
  
  WORKDIR /app
  
  ADD . /app
  
  EXPOSE 8080
  
  RUN ./gradlew build
  
  CMD ./gradlew bootRun
  </code></pre>
  
  <p>When I just build the app with "gradlew build" it runs and when I try to run this Docker Image with a Mac, it works too, just not for windows</p>
  
  <p>EDIT: </p>
