Trigger a Jenkins pipeline by tagging an existing

问题:

Description

I have Jenkins (2.126) set up to build a pipeline when a new tag is pushed. Specifically, I want to tag an existing commit on master as release-3 and have it trigger a build. According to several sources, what I want is possible:

Unfortunately, nothing happens when I tag an existing commit and push it to the Git repository. Other builds (triggered by branches) work as expected, and the tag-triggered build in question completes successfully when started manually.

According to some, tag-triggered pipelines should work since version 2.3. Is there anything I can configure to make it work?

You can use Generic Webhook Trigger Plugin.

In GitHub:

1. Set a webhook in GitHub to invoke JENKINS_URL/generic-webhook-trigger/invoke?some-token-here

In Jenkins:

1. Create a job and enable the Generic Trigger under "Triggers"
2. Configure a variable named ref with JSONPath $.ref
3. Set the filter text to $ref
4. Set the filter regexp to ^(refs/tags/.+)$
5. Set the token to some-token-here

Now when a tag is pushed to the repo this job will trigger.

You may also want to pick other values from the webhook like $.repository.ssh_url to get the SSH clone URL.
