如何通过PR评论结合Post Webhooks for Bitbucket触发Jenkins多分支任务

Got it, let's walk through exactly how to set this up so your task runs only when someone comments "run this again" on a Bitbucket PR using the Post Webhooks for Bitbucket plugin.

Step 1: Enable the Comment Event #

First, confirm you’ve toggled on the Pull request commented option in your webhook configuration (you mentioned you spotted this, so just make sure it’s enabled alongside your existing "created" and "re-scoped" events).

Step 2: Add a Payload Filter for Target Comment Text #

The magic here is filtering the webhook to only fire when the comment matches your exact phrase. Most versions of this plugin include a Payload Filters or Conditions section where you can define rules based on Bitbucket’s webhook JSON payload.

Here’s the exact filter setup you need:

• In your webhook settings, find the "Payload Filters" section and add a new rule.
• Set these values:
  • Path: comment.content.raw (this targets the unformatted raw text of the PR comment in Bitbucket’s payload)
  • Operator: Contains (use Equals if you want an exact, case-sensitive match; "Contains" works for slight variations like extra spaces)
  • Value: run this again (your target comment trigger phrase)

Step 3: Verify the Payload Path (Optional) #

If you’re unsure about the payload path, you can capture a test payload using a webhook testing tool or by checking your task runner’s logs. Look for the comment object in the JSON response—you’ll see the raw comment text under content.raw.

Step 4: Test the Setup #

Create a test PR, leave a comment with "run this again", and check if your task triggers. If it doesn’t, double-check:

• The filter path is spelled correctly (case sensitivity might matter depending on your plugin settings)
• The "Pull request commented" event is still enabled
• Your task runner is properly listening for the webhook signal

Example Rule (Visual Builder Version) #

If your plugin uses a drag-and-drop rule builder, it might look like this:

IF comment.content.raw CONTAINS run this again THEN trigger webhook

That’s all you need! This setup ensures the webhook only sends a trigger when your specific comment phrase is used, rather than firing on every PR comment.
