Expected Behavior

Gradle supports Oracle JDK 9 fully.

Current Behavior

Gradle doesn't support Oracle JDK 9 fully.

Context

JDK 9 final has been released, however, looks like Gradle isn't fully compatible with it.

This is due to the usage of new ElementType.MODULE. Groovy 2.4.12 seems to support MODULE but 2.4.11 doesn't.

Steps to Reproduce (for bugs)

Install Oracle JDK9, and run ./gradlew check in Gradle project.

$ ./gradlew check -s
Parallel execution is an incubating feature.

@BeneStem Thanks for reporting. That's just warning. Groovy uses too much reflection and Java 9 is much more restrictive concerning reflective access to non-public fields/methods. However, there's still something we can try to remove this warning.

@donhuvy @BeneStem Thanks for reporting. Actually this warning is on Groovy side and there's not much we can do. You can add the following arguments to java bootstrap script or JAVA_OPTS to suppress this warning:

--add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.invoke=ALL-UNNAMED

@dginovker The issue was that the build would fail. The warnings are expected and we can do nothing about them until Groovy somehow works around the new JDK limitations (or the JDK offers a better API for Groovy to use).

Clearly the problem is with Groovy. Is there a matrix someplace showing what versions of Groovy work with Java 10 (aka 18.03 -- Java 9 is superseded)?

With Groovy 6.4.12 and Gradle 4.4 with the JAVA_HOME pointed to Java 10 JDK

I switched back to Java 8 JDK. I guess i can build with Java 10 compiler. Just can't build any of my Groovy code. The Groovy download page confused me. There are many different versions and betas. They must be overstaffed on that project.

An interesting point though. I only changed my JAVA_HOME to point to the Java 8 JDK and I see this:

tried Groovy 2.4.14, which seems to be latest release version. Fails on Java 10.

Update -- The relevant Groovy project issue is here:

I suggest we get behind it as it has a low priority, it seems. As it has been CLOSED.

@aplatypus @mindthump @nshusa @goldparrot That's not an error but a warning that will eventually be resolved in Groovy for good. This issue was about making Gradle fully compatible with Java 9 and upgrading to 2.4.12 which has both been done.

In Java 10, this is an error, not just a warning.

This issue is not about Java 10. This can only be fully resolved by a major version upgrade for Groovy, which we can only do in Gradle 5.0.

@oehme I guess this not currently in the 5.0 nightly build, as i'm still receiving errors.

Groovy has not been fixed, so nothing to upgrade on our side. I'm tempted to just filter the warnings out for now, since there is nothing we or the user can do.
