Fixes #11997. Supersedes #12003 (its commits are included).

Spotless 6.22.0 passes --scripts-prepend-node-path to npm, which current npm rejects, so the prettier step fails. This upgrades Spotless to 8.10.1 and lets Dependabot update it together with the other root Gradle plugins.

Spotless 8 broke CI matrix generation. testMatrix depended on every check task, so Greclipse ran and printed to stdout, the matrix JSON became invalid, and jq failed, which skipped all downstream jobs. Now:

• testMatrix only lists the check tasks without running them. The no-op test executor hack, which used an internal Gradle API, is removed.
• CI writes the matrix to a file (-PtestMatrixOutput) and checks that it is a non-empty list of task paths.
• greclipse is only configured in projects with Groovy sources (spock and its docs example). Spotless downloads greclipse's Eclipse P2 dependencies even when nothing matches, so every module job fetched them uncached from Eclipse's servers, which made CI flaky.

Summary by CodeRabbit

• Build & CI
  • Automated build workflows now validate selected test tasks and report errors when expected tasks are missing or invalid.
  • Formatting checks use an updated tool version, and Groovy formatting runs only when applicable files are present.
• Dependency Updates
  • Automated dependency updates now include the formatting tool.

📝 Walkthrough

The pull request updates Spotless to version 8.10.1, adds Dependabot support for Spotless updates, and makes Groovy formatting configuration conditional on Groovy source files. It also changes Gradle test-matrix output handling and validates task lists for CI job matrices.

Changes: Gradle CI test-matrix generation

Layer / File(s)	Summary
Test-matrix output and CI validation gradle/ci-support.gradle, .github/workflows/ci.yml	The testMatrix task can write JSON task data to a file and no longer depends on collected check tasks. CI validates task arrays and filtered results before creating job matrices. The task-graph hook that disabled other tasks was removed.

Spotless updates

Layer / File(s)	Summary
Spotless version and formatting configuration build.gradle, examples/build.gradle, smoke-test/build.gradle, gradle/spotless.gradle	The builds declare Spotless version 8.10.1. Groovy formatting configuration applies only when a Groovy source file exists under src.
Dependabot update configuration .github/dependabot.yml	Dependabot allows updates for com.diffplug.spotless.

Full details: Linked Issues check

Explanation

Issue [#11997] requires Spotless 8.10.1 or later to remove npm's rejected --scripts-prepend-node-path flag. The PR updates the Spotless plugin to 8.10.1 in the root, examples, and smoke-test Gradle plugin declarations. The CI changes also validate the generated test matrix as a non-empty list of Gradle task paths and avoid executing check tasks while generating it. No linked coding requirement remains unmet.

Full details: Out of Scope Changes check

Explanation

The changes stay connected to the Spotless upgrade and its CI effects. The testMatrix output file and validation prevent Spotless or Greclipse output from corrupting matrix JSON. Conditional greclipse configuration prevents unnecessary Eclipse dependency downloads. Dependabot configuration keeps the root Spotless plugin update grouped with other Gradle plugins. No unrelated change is demonstrated.
