            state: FAILED
            name: "unit test"

Behavior

check: Check for changes to all pull requests.

The current open pull requests fetched from Bitbucket server for given project and repository. Update time are compared to the last fetched pull request.

If any pull request are new or updated or removed, a new version is emitted.

in: Fetch the commit that changed the pull request.

This resource delegates entirely to the in of the original Git resource, by passing through source.git to source of the original git-resource, then specifying source.branch as the branch that changed, and version.ref as the commit on the branch.

Parameters

All params, except the ones listed below, will be passed through to params of the original git-resource.

  • skip_download: Optional. Skip git pull. Artifacts based on the git will not be present.
  • fetch_upstream: Optional. Also fetch the pull requests' upstream ref. This will overwrite the fetch param.

out: Update the PR.

Behavior depends on the value of parameter action, where is the values are:

  • change-build-status: Change the commit build status.

    • action: Required. For this behavior should be change-build-status.
    • Parameters except the name will be respected the Bitbucket documentation.
    • name: Deprecated. Parameter is deprecated and has been left only for backward compatibility.
    • repository: Optional. The path of the source repository for changing build status.
  • push: Push the commit to pull request branch.

    • action: Required. For this behavior should be push.
    • repository: Optional. The path of the source repository for pushing.

Troubleshooting

  • Mark PR with "build started" creates a new version of a PR.

    The Concourse is not available to skipping versions but have the workaround. You should add the resource with the same settings as pull-request for changing the build status only.

    - name: test-pull-requests
      plan:
      - get: pull-request
        trigger: true
        version: every
      - get: node
      - put: pull-request-status
        params:
          action: change-build-status
          state: INPROGRESS
          key: concourse-build
