# This workflow runs after the completion of the CI workflow triggered on a "pull_request" event.
# The "pull_request" event type is run in an unprivileged context without access to the repository
# secrets. This means that PRs from public forks cannot publish Gradle Build Scans or modify the
# PR contents.
#
# This "workflow_run" triggered workflow is run in a privileged context and so does have access to
# the repository secrets. Here we can download the build scan files produced by a PR and publish
# them to develocity.apache.org.
#
# If we need to do things like comment on, label, or otherwise modify PRs from public forks. This
# workflow is the place to do it. PR number is ${{ github.event.workflow_run.pull_requests[0].number }}
