mx build error

[Sidharth]

Hello All Graal Developers,

I am new to mailing lists so bear with me if I have made some kind of a mistake in posting the issue I am facing currently.

I have set JVMCI_VERSION_CHECK=ignore and am using java-9-openjdk-amd64 in a ubuntu 64 bit OS.

running 'mx build' is throwing this error

javac: invalid flag: --add-exports java.base/jdk.internal.module=ALL-UNNAMED
Usage: javac <options> <source files>
use -help for a list of possible options
javac: no source files
Usage: javac <options> <source files>
use -help for a list of possible options
failed to compile:/media/sanjai/7A84227E84223D4F/graal/mx/ListModules.java

Can someone help me with this, I am stuck here for sometime.

Regards,
Sid
