Opening this PR to debug why the #160 CI is failing with this error message from Gradle

 * What went wrong:
Execution failed for task ':compileJava'.
> No value present

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

I'm guessing that the tests started failing due to the recent Gradle v7.0 release

 Welcome to Gradle 7.0!

Here are the highlights of this release:
 - File system watching enabled by default
 - Support for running with and building Java 16 projects
 - Native support for Apple Silicon processors
 - Dependency catalog feature preview

For more details see docs.gradle.org/7.0/release-notes.html

Starting a Gradle Daemon (subsequent builds will be faster)

Looks like we need to

• add support for Gradle 7
• add support to test specific versions of Gradle. Currently we only use the latest version.
