Pull Request Notifier for Bitbucket Server

This project is sort of deprecated. See: https://community.developer.atlassian.com/t/eula-and-data-center-for-free-apps/26062

This is a Bitbucket Server plugin that can invoke custom URL:s, supporting variables, when configured events occur on pull requests in Bitbucket Server. It can notify Jenkins, Bamboo, TeamCity, HipChat and many more!

The original use case was to trigger Jenkins jobs to build and verify pull requests but it can trigger any system. The plugin can notify any system that can be notified with a URL.

Here is a screenshot of the admin GUI on global level. And here is a screenshot of the admin GUI on repository level.

Here is a blog post that includes the plugin.

Features

The Pull Request Notifier for Bitbucket Server can:

• Invoke any URL, or set of URL:s, when a pull request event happens.
  • With variables available to add necessary parameters.
  • HTTP POST, PUT, GET and DELETE. POST and PUT also supports rendered post content.
• Be configured to trigger on any pull request event. Including extended events:
  • RESCOPED_FROM, when source branch change
  • RESCOPED_TO, when target branch change
  • BUTTON_TRIGGER, when trigger button in pull request view is pressed
• Can invoke CSRF protected systems, using the ${INJECTION_URL_VALUE} variable. How to to that with Jenkins is described below.
• Be configured to only trigger if the pull request matches a filter. A filter text is constructed with any combination of the variables and then a regexp is constructed to match that text.
• Add buttons to pull request view in Bitbucket Server. And map those buttons to URL invocations. This can be done by setting the filter string to ${BUTTON_TRIGGER_TITLE} and the filter regexp to title of button.
  • Buttons can have forms associated with them, and then submit the form data using the ${BUTTON_FORM_DATA} variable.
• Authenticate with HTTP basic authentication.
• Optionally allow any SSL certificate.
• Use custom SSL key store, type and password.
• Send custom HTTP headers
• Can optionally use proxy to connect
• Can let users and/or admins do configuration. Or restrict configuration to just system admins. A user will have to browse to the configuration page at http://domain/bitbucket/plugins/servlet/prnfb/admin.
• Can enable trigger
  • If PR has, or has no, conflicts
  • Only if PR has conflicts
  • Only if PR has no conflicts
• Nice configuration GUI.
  • Global at /bitbucket/plugins/servlet/prnfb/admin
  • Project level at /bitbucket/plugins/servlet/prnfb/admin/PROJECT_1
  • Repo level at /bitbucket/plugins/servlet/prnfb/admin/PROJECT_1/rep_1

The plugin has its own implementation to create the RESCOPED_FROM and RESCOPED_TO events. RESCOPED is transformed to RESCOPED_TO if target branch changed, RESCOPED_FROM if source branch, or both, changed.

The filter text as well as the URL support variables. These are:

The ${PULL_REQUEST_USER...} contains information about the user who issued the event. Who commented it, who rejected it, who approved it...

You may want to use these Jenkins plugins if you are notifying Jenkins:

• Generic Webhook Trigger Plugin To trigger the build.
• Violation Comments to Bitbucket Server Plugin to report results form static code analysis.
• StashNotifier Plugin to report build status back to Bitbucket Server.

Integration guides

Generally, when fiddling with this plugin, you may want to use something like RequestBin. Let the notification URL point to it and you can inspect what the invoked URL looks like.

Here are some guides on how to use the plugin with different systems. Feel free to add guides through pull requests to this repo!

• Azure Pipelines
• HipChat
• Jenkins
• Slack
• TeamCity

Button Forms

For each button you can specify a form that will show up when the button is pressed. That form data will then be submitted and will be available in the ${BUTTON_FORM_DATA} variable. Additionally, the form itself can reference other variables (with the exception of the ${BUTTON_...} ones) and will have those resolved prior to rendering.

A form is defined as a JSON array. Here is an example that shows all possibilities:

[
        {   "name": "var1",
            "label": "var1 label",
            "defaultValue": "you can put a variable like this: ${PULL_REQUEST_AUTHOR_NAME}",
            "type": "input", 
            "required": false,
            "description": "var1 description"
        },
        {   "name": "var2",
            "label": "var2 label",
            "defaultValue": "any string can go here",
            "type": "textarea", 
            "required": false,
            "description": "var2 description"
        },
        {   "name": "var3",
            "label": "var3 label",
            "defaultValue": "option2_name",
            "buttonFormElementOptionList": [
                {"label": "option1 label", "name": "option1_name"},
                {"label": "option2 label", "name": "option2_name"},
                {"label": "option3 label", "name": "option3_name"}
            ],
            "type": "radio", 
            "required": true,
            "description": "var3 description"
        },
        {   "name": "var4",
            "label": "var4 label",
            "type": "checkbox", 
            "required": true,
            "buttonFormElementOptionList": [
                {"label": "option1 label", "name": "option1_name", "defaultValue": true}, 
                {"label": "option2 label", "name": "option2_name", "defaultValue": true}
            ],
            "description": "var4 description"
        }
]

You can see a screenshot here when rendered.

When submitted with the default values, it will look like this:

{
   "var1":"you can put a variable like this: admin",
   "var2":"any string can go here",
   "var3":"option2_name",
   "var4":[
      "option1_name",
      "option2_name"
   ]
}

REST API

Some rest resources are available. You can figure out the JSON structure by looking at the DTO:s.

• /bitbucket/rest/prnfb-admin/1.0/settings

  • GET Get all global settings.
  • POST Store all global settings.

• /bitbucket/rest/prnfb-admin/1.0/settings/notifications

  • DELETE /{uuid} Deletes notification with uuid.
  • GET Get all notifications.
  • GET /{uuid} Get notification with uuid.
  • GET /projectKey/{projectKey} Get all notifications for the project.
  • GET /projectKey/{projectKey}/repositorySlug/{repositorySlug} Get all notifications for the project and repository.
  • POST Save a notification.

• /bitbucket/rest/prnfb-admin/1.0/settings/buttons

  • DELETE /{uuid} Deletes button with uuid.
  • GET Get all buttons that the current user is allowed to use.
  • GET /{uuid} Get button with uuid.
  • GET /repository/{repositoryId}/pullrequest/{pullRequestId} Get all buttons for repository that the current user is allowed to use.
  • GET /projectKey/{projectKey} Get all buttons for the project.
  • GET /projectKey/{projectKey}/repositorySlug/{repositorySlug} Get all buttons for the project and repository.
  • POST Save a button.
  • POST {uuid}/press/repository/{repositoryId}/pullrequest/{pullRequestId} Press the button.

A new notification to trigger on COMMENTED can be added like this.

curl -u admin:admin 'http://localhost:7990/bitbucket/rest/prnfb-admin/1.0/settings/notifications' -H 'Content-Type: application/json; charset=UTF-8' -H 'Accept: application/json, text/javascript, */*; q=0.01' --data-binary '{"uuid":"","name":"","projectKey":"","repositorySlug":"","filterString":"","filterRegexp":"","triggers":["COMMENTED"],"injectionUrl":"","injectionUrlRegexp":"","user":"","password":"","proxyUser":"","proxyPassword":"","proxyServer":"","proxyPort":"","url":"http://localhost:80/?abc","method":"GET","postContent":"","headers":[{"name":"","value":""}]}'

It will respond with something like this.

{"headers":[],"method":"GET","name":"Notification","triggerIfCanMerge":"ALWAYS","triggerIgnoreStateList":[],"triggers":["COMMENTED"],"url":"http://localhost:80/?abc","uuid":"b1306a3a-5a87-4145-80b7-660bc986dd25"}

It can then be changed to trigger on RESCOPED_FROM and RESCOPED_TO like this.

curl -u admin:admin 'http://localhost:7990/bitbucket/rest/prnfb-admin/1.0/settings/notifications' -H 'Content-Type: application/json; charset=UTF-8' -H 'Accept: application/json, text/javascript, */*; q=0.01' --data-binary '{"uuid":"b1306a3a-5a87-4145-80b7-660bc986dd25","name":"Notification","projectKey":"","repositorySlug":"","filterString":"","filterRegexp":"","triggerIfCanMerge":"ALWAYS","triggers":["RESCOPED_FROM","RESCOPED_TO"],"injectionUrl":"","injectionUrlRegexp":"","user":"","password":"","proxyUser":"","proxyPassword":"","proxyServer":"","proxyPort":"","url":"http://localhost:80/?abc","method":"GET","postContent":"","headers":[{"name":"","value":""}]}' --compressed

It will respond with something like this.

{"headers":[],"method":"GET","name":"Notification","triggerIfCanMerge":"ALWAYS","triggerIgnoreStateList":[],"triggers":["RESCOPED_FROM","RESCOPED_TO"],"url":"http://localhost:80/?abc","uuid":"b1306a3a-5a87-4145-80b7-660bc986dd25"}
