I get a little further by doing the following:

1.  export GRADLE_OPTS=--add-exports-private
java.base/java.lang=ALL-UNNAMED --add-exports-private
java.base/java.util=ALL-UNNAMED

2.  add the same options above to the "org.gradle.jvmargs" in
gradle.properties

3.  in buildSrc/build.gradle add

if (JavaVersion.current().java9Compatible) {
    allprojects {
        tasks.withType(GroovyCompile) {

groovyOptions.forkOptions.jvmArgs.addAll(['--add-exports-private',
'java.base/java.lang=ALL-UNNAMED'])
        }
        test {
            jvmArgs '-addmods', 'java.xml.bind'
        }
    }
}

After that it starts to fail resolving methods used in the gradle build
files.
