How am I supposed to compile CInterfaceTutorial.java & cinterfacetutorial.c?

[MicroGery]

I'm new to Graal&Native-image, and I'm facing a problem of Java calling C interfaces. As it said in thread title, then I found ther were examples in the code: graal-master\substratevm\src\com.oracle.svm.tutorial\src\com\oracle\svm\tutorial
I'm wondering that how can I compile and run this example. Thanks
