Tentei com um "paralelo" em https://github.com/Howchoo/alexa-avs-sample-app.git
Porém aparece o seguinte erro quando executo mvn exec:exec :
-Xbootclasspath/p is no longer a supported option.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
