Building GraalVM upon JDK 11

[Yifei Zhang]

Dear all,
I am trying to build Graal suites other than compiler (e.g., substratevm, graaljs) based on JDK 11. The following commands are executed under the grail/vm directory:

$ export JAVA_HOME=/jdk11
$ export EXTRA_JAVA_HOMES=/jdk8
$ mx --dynamicimports /substratevm,/graal-nodejs build

But building fails. It seems that mx is trying to find some files, such as jvmci-services.jar, under the directory $JAVA_HOME/jre/lib, which does not exist in JDK 11.
I was wondering if the building commands above are correct. Is there anyone trying to build Graal upon JDK 11? Does anyone encounter the same issue?

Cheers,
Yifei
