The Stormpath Java SDK API .jar provides a Java API that your code can use to make calls to the Stormpath API. This .jar is the only compile-time dependency within the Stormpath SDK project that your code should depend on. Implementations of this API (implementation .jars) should be runtime dependencies only.
