Summary

Configures Maven Central release staging for google/TestParameterInjector through Google's OSS Exit Gate (test-param-inj/mavencentral).

Key Changes

• Artifact Registry Staging Target: Stages release artifacts to us-maven.pkg.dev/oss-exit-gate-prod/test-param-inj--mavencentral via the oss-exit-gate publishing profile/repository (leaving normal builds, unit tests, and snapshot workflows unaffected).
• Preemptive Staging Cleanup & Release Manifest: Before publishing a new release, stale packages in test-param-inj--mavencentral should be cleaned via gcloud artifacts packages list/delete, followed by uploading manifest.json ({"publish_all": true}) to gs://oss-exit-gate-prod-projects-bucket/test-param-inj/mavencentral/manifests/ to trigger OSS Exit Gate verification and Maven Central publication:

  # 1. Clean up stale releases from staging repo
  packages=$(gcloud artifacts packages list \
      --project="oss-exit-gate-prod" \
      --location="us" \
      --repository="test-param-inj--mavencentral" \
      --format="value(name)" 2>/dev/null)
  echo "${packages}" | xargs -r -I {} sh -c '
      gcloud artifacts packages delete "{}" \
          --project="oss-exit-gate-prod" \
          --location="us" \
          --repository="test-param-inj--mavencentral" \
          --quiet
  '
  
  # 2. Stage signed artifacts & upload release manifest
  mvn deploy -P sonatype-oss-release,oss-exit-gate
  echo '{"publish_all": true}' > /tmp/manifest.json
  gcloud storage cp /tmp/manifest.json \
      "gs://oss-exit-gate-prod-projects-bucket/test-param-inj/mavencentral/manifests/manifest-$(date +%s).json"

• Verification: OSS Exit Gate resources (test-param-inj--mavencentral) are provisioned and end-to-end Artifact Registry + GCS manifest smoke testing has been verified (HTTP 201 + rc=0).
