I've downloaded the deeplearning4j examples as descriped in the quickstart guide using git and maven. When I try to start an example with IntelliJ there comes up an Error.

I tried to add some more dependencys in my pom.xml but dont find the right one. On top there there are many(!) warnings about deprecated classes, followed by an Error:

Error:(7, 27) java: package com.sun.media.sound does not exist

Error:(43, 13) java: cannot find symbol symbol: class AudioSynthesizer location: class org.deeplearning4j.examples.recurrent.character.harmonies.Midi2WavRenderer

I use the JDK12, latest maven and examples.

On IntelliJ/File/Project Structure.../Project Settings/Project/Project SDK select, say, Java version 1.8, would solve this problem.

Deeplearning4j depends on com.sun.media.sound package to compile. Since recent IntelliJ comes with JDK 11 as default, which does not include such package. You have to install JDK version 8, which include the above mentioned package, then manually select JDK8's installation location under IntelliJ's File/Project Structure.../Project Settings/Project/Project SDK. My Deeplearning4j project can be compiled successfully after such modification. Good luck!
