Override build number in your Azure pipeline

Written by aerokhin on September 23, 2020 Categories: azure, bash, programming

If you are using Azure DevOps, the build number is generated for you automatically based on the current date and you end up with something like 20200923.4 (meaning it was a 4th build on 23rd of September). Frankly, this is not very descriptive.

Good thing – you can override it using special logging commands. The command we are looking for is ##vso[build.updatebuildnumber] and it can be executed from your pipeline.

All is needed is to include a step with the following bash script:

  - bash: |
      echo "##vso[build.updatebuildnumber]Release $(Version)"
    name: SetReleaseBuildName

$(Version) is set during one of the previous steps. You can configure it based on your requirements or preferences.


Some additional notes:

  • build will start with a default number, it will be overwritten only after execution of the specified step;
  • the maximum length of a build number is 255 characters;
  • it is forbidden to use following characters in build number: ‘“‘, ‘/’, ‘:’, ‘<’, ‘>’, ‘\’, ‘|’, ‘?’, ‘@’, and ‘*’.
