How do I fetch a Jenkins build's console output?
Short answer: You can get jenkins build log in Jenkins by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Jenkins Get Jenkins Build Log action to a workflow, map its 2 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.
Inputs
The fields this action accepts.
Every field can be mapped from an upstream trigger, AI step, table row, or hard-coded literal.
| Field | Type | Required | Description |
|---|---|---|---|
Job Name job_name | string | Required | Job Name |
Build Number build_number | string | Required | Build Number. Example: 42 or lastBuild |
Sample request
{"job_name": "{{trigger.job_name}}","build_number": "e.g. 42 or lastBuild"}
Returns
{"url": "https://jenkins.example.com/job/my-project/42/","result": "SUCCESS","building": false,"duration": 45000,"timestamp": 1712835600000,"displayName": "#42"}
Use these fields in downstream nodes for routing, logging, or error handling.

FAQ
Questions about Get Jenkins Build Log.
What does the Get Jenkins Build Log action do in Jenkins?
Returns the full stdout/stderr of the build as plain text. For "post error log to Slack on deploy failure" diagnostic workflows. For very long logs, use the progressiveText endpoint via HTTP action for streaming.
What inputs does Get Jenkins Build Log require?
Required: Job Name, Build Number. Every input accepts a static value or a variable from any upstream node in your workflow.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if Jenkins returns an error?
The run history shows the failed step with its input and the error message Jenkins returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.
Does Get Jenkins Build Log support batch operations?
Run Get Jenkins Build Log inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Jenkins's rate limits.

Get Jenkins Build Status
Returns the current state of a specific build number — queued, building, success, failure, aborted. The standard polling lookup after Trigger Build.
ActionList Jenkins Jobs
Returns every job visible on the Jenkins instance organised by folder. Useful for resolving job paths at workflow setup or for inventorying the CI configuration.
ActionTrigger Jenkins Build
Starts a job optionally with parameters. Returns a queue item ID; the actual build number assigns when the queue dequeues. For "Linear issue moved to staging → trigger deploy job" or "external event → CI run" workflows.
