Can we run it on Linux?

Hi,

Thanks for sharing this open source PM implementation. I'm trying to run it on an Ubuntu 18.04 machine, and I'm getting the following error:

$ mvn clean package install -X

Java version is 1.8.0_131:

$ java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

Any clues for something I'm missing? Or maybe it just isn't prepared to run on Linux at all?
