Purpose

At times, you may want to save the logs from a Bamboo build as an artifact. Bamboo doesn't do this automatically, so this article describes a way to achieve this.

Solution

To download the build log, you can add a Script task with a curl command, which will download it.

1. From your Plan configuration, take note of the Build key(s) you want to save the build log output. The format is <PROJECT-PLAN-JOB>

2. Create a new Stage at the end of your Build – this will ensure that you capture as much of the previous job as you can

3. If you want this to run regardless of the state of other Stages, make sure to select the Final Stage checkbox

4. Add a Script task to your new Stage, containing the following command:

   # _build_key is the Job you want to have its output saved
   _build_key="PROJ-PLAN-JOB"
   _output_file="build-log.txt"
   _credentials="admin:admin"
   _bamboo_url="https://bamboo.mydomain.net"
   curl -s -k -u${_credentials} ${_bamboo_url}/download/${_build_key}/build_logs/${_build_key}-${bamboo.buildNumber}.log > ${_output_file}

5. Add an Artifact definition for <build-log.txt> to the Job
