Hello Anton,

We currently don't have a shortcut like that in the build system, you 
basically have to build everything. Once everything is built you can use 
jlink to create your own custom image with just the modules you like.

If you run "make java.base", you will get a runnable "exploded" image in 
build/<foobar>/jdk that contains what you just built and nothing more. 
Perhaps that's enough for what you need?

/Erik
