Fix compatibility with Gradle's configuration cache (#339)

* Use serializable lambdas

This is an attempt to fix #338

* Fix compatibility with the configuration cache

In the process, this commit removes use of deprecated Gradle APIs
and therefore bumps the minimal version of Gradle to 7.4. The
configuration cache tests only pass on Gradle 7.5+, which is
reasonable given that it's an experimental feature.

* Disable test
