Simple MPRIS 2.2 implementation with Kotlin for the JVM.
Code is basically done, but largely untested. No guarantees or liabilities - MIT License.
The project is separated into two modules, the base/root module and mpris-extensions, which is meant to ease the use of this library by providing reference implementations and abstractions. While the base module should be compatible with any JVM language, the extensions module is specifically developed for Kotlin.
A test implementation can be found in extensions/test/xerus/mpris/MPRISPlayer.kt, which should be executable from within your IDE after syncing with gradle via ./gradlew build.
