Add helpers to run Gradle TestKit with --configuration-cache and assert store/reuse. The acceptance test stays @ignore until the plugin is CC-safe.
Convert ScoverageReport and ScoverageAggregate to abstract task types with Property getters so task state is wired explicitly from the plugin.
Move coverage verification into CheckScoverageTask and identical-class cleanup into PruneIdenticalScoverageClassesTask. Resolve scalac plugin jars in compileScoverageScala doFirst without referencing Project.
Register instrumented test tasks instead of mutating test classpath in taskGraph.whenReady. Report tasks depend on scoverageTest; functional tests that filter coverage measurement target scoverageTest explicitly.
Register root aggregateScoverage when the plugin is applied to a parent project and connect subprojects via plugins.withId instead of projectsEvaluated.
Move scoverage artifact wiring into configureScoverageDependencies so dependency resolution stays isolated from task graph configuration.
Enable CC functional tests with stable store/reuse assertions, document scoverageTest companions and CC support, harden plugin closures for CC serialization, and run CI with --configuration-cache.

thanks - this looks interesting but I worry that the change in behaviour is essentially reverting #57. I suppose that mutating the classpath breaks configuration caching? |

Summary
Gradle 9 configuration cache support via typed tasks,
scoverageTestcompanion tasks, and configuration-time aggregate wiring. ReplacesdoLastcheck/prune logic withCheckScoverageTaskandPruneIdenticalScoverageClassesTask. CI runs with--configuration-cache.Behavioral change
Coverage no longer mutates the
testclasspath. UsescoverageTest(orscoverageIntTest, etc.) for instrumented runs, e.g.scoverageTest --tests ....Review guide
