Upgrading the JDK 9-based build to use JDK 9.0.4 has revealed that
Gradle 4.0.x doesn't work with it as it fails to parse the 9.0.4
version number.
This commit disables building the Gradle plugin on Java 9 (as we
had already done for Java 10) until we decide what to do
(see gh-12333).
Previously, the JDK 10 build would fail as we build the plugin using
Gradle 4.0.x (the lowest version of Gradle that we support) and
Gradle 4.0.x doesn't work with Java 10.
Upgrading to Gradle 4.1, which appears to work with Java 10, was
considered but rejected for now as it introduces the risk that we
inadvertently use an API that's new in 4.1 and break our 4.0 support.
This commit goes for the extreme option and disables building the
Gradle Plugin when building with JDK.

Travis is terminating builds as they are producing too much logging.
A major contributor to the volume of logging is the Gradle plugin's
build. This commit switches off debug logging for the build and
enables test event logging. This considerably reduces the volume of
logging that is produced while still providing some insight into the
build's tests.
