How to use compiled source GraalVM to run a Java program?

Question

I built the GraalVM JVM code from the project repository ( GraalVM ), using the following instructions . I think it completed successfully (didn't see any error messages), and it created a new folder graal\\vm\\mxbuild with what seems to be the compilation product.

My question is, how do I use the compiled JVM to run a java program? usually I would expect some java execution file, but I can't find any.

My goal is to eventually change the JVM code in order to test the behavior of the GC, so if there is a different way to do it with the GraalVM source code I'll appreciate your instructions.

(working on an Ubuntu 18.04 system if it matters..)

Answer 1

The jdk product files can be found in the following folder: graal/sdk/mxbuild/linux-amd64/GRAALVM_CE_JAVA8/graalvm-ce-java8-20.1.0-dev

It is possible to use the command mx --env ce graalvm-home to find the jdk files.

Another thing I found out and maybe can be helpufl for someone in the future, is that it is possible to work and compile only on the jvm project under the Graal project. I order to do so, use the code in graal-jvmci-8 repository .
