-This is [resolved in GitLab 12.10](https://gitlab.com/gitlab-org/gitlab/-/issues/209070).

 ## Limitations
 
 A parent pipeline can trigger many child pipelines, but a child pipeline cannot trigger
 further child pipelines. See the [related issue](https://gitlab.com/gitlab-org/gitlab/issues/29651)
 for discussion on possible future improvements.

+When triggering dynamic child pipelines, if the job containing the CI config artifact is not a predecessor of the

+In the future we want to validate the trigger job's dependencies [at the time the parent pipeline is created](https://gitlab.com/gitlab-org/gitlab/-/issues/209070) rather than when the child pipeline is created.

To automate this process, we use the [license_finder][license_finder] gem by Pivotal.

 There are some limitations with the automated testing, however. CSS, JavaScript, or Ruby libraries which are not included by way of Bundler, NPM, or Yarn (for instance those manually copied into our source tree in the `vendor` directory), must be verified manually and independently. Take care whenever one such library is used, as automated tests won't catch problematic licenses from them.
