 If your build publishes a [build scan](https://gradle.com/build-scans/) the `gradle-command-action` action will emit the link to the published build scan as an output named `build-scan-url`.
 
 You can then use that link in subsequent actions of your workflow.

+For example:
+
+```yaml
+// .github/workflows/gradle-build-pr.yml
+name: Run Gradle on PRs
+on: pull-request
+jobs:
+  gradle:
+    strategy:
