title: Can I use java8 language for Robolectric tests, while using java7 for the app?
body: <p>Basically, I want to use all the java8 features for unit tests, since they run on the jvm, while maintaining compatibility for app by only using java7 language features.</p>
  
  <p>However, I only see one place in build.gradle where I can set the language version, and it applies to both the app and its tests.</p>
