Triggering a build only on a failed build of another build configuration

Question

• There are two build configurations: buildA and buildB.
• The new build of buildB should be triggered only when the build of buildA fails.

Is it possible to achieve this scenario?

Answer

There is no built-in functionality to trigger the build of the build configuration buildB only if the build of the configuration buildA failed.

To achieve a similar logic, it is possible to use the Finish Build trigger to trigger buildB on all builds of buildA. In buildB, create a build step to check the status of the previous build of buildA and cancel itself if it was successful.

This can be achieved using the REST API:

• The status of the last build of any build configuration can be retrieved from the following endpoint:

GET /app/rest/builds?locator=buildType:<target build configuration ID>,count:1

• A running build can be canceled as described here: Cancel Started Build.
