title: How to specify the JDK compile level of a module in Gradle
body: <p>I have a pure Java module in an Android project. My project compiles by default using JDK 8, but I want my Java module to compile using JDK 7. How do I specify for my pure java module a compile level of 1.7? Keep in mind that I am not wanting to override the project level compile level of 1.8.</p>
