The best suggestion I can give is is to use a multi module setup.

Furthermore I'm not sure if you really need toolchains in your case?.

Kind regards

I've taken a slimmed down _Multi-Release Parent_ 
 approach, and 
the main compilation and packaging seems just right:


     
     maven-compiler-plugin
     3.10.1
     
     8
     8
     
     
     
     compile-java9
     compile
     
     compile
     
     
     9
     
     9
     
     
 
${project.basedir}/src/main/java9

     
     true
     
     
     
     
     
     maven-jar-plugin
     3.2.2
     
     
     
     true
     
     
     
     

Now I've added some test sources exercising the Java 9+ only classes, 
but the `testCompile` goal seems unable to find them.  Is it possible to 
configure the `default-testCompile` execution to see the classes from 
the `multiReleaseOutput` of the main compile?


FWIW, my current work-in-progress could be seen at:

testCompile with multiReleaseOutput main classes
