I can't seem to run jacoco plugin in gradle with Java 10. Is this a known issue?

So I checked out the code to build with Java 10 and the following modifications:

diff --git a/org.jacoco.build/pom.xml b/org.jacoco.build/pom.xml

And setting the JAVA_HOME to the JDK10 home (on macos)

The build fails on the JaCoCo Maven plugin 0.8.1-SNAPSHOT:
