-CAUTION: **Caution:**
-Before GitLab 11.5, Code Quality job and artifact had to be named specifically to

-For GitLab 11.5 and later, the job should look like:
-
-```yaml
-code_quality:
-  image: docker:stable

-    DOCKER_DRIVER: overlay2
-  allow_failure: true
-  services:
-    - docker:stable-dind

-In GitLab 12.6, Code Quality switched to the
-[new versioning scheme](https://gitlab.com/gitlab-org/ci-cd/codequality#versioning-and-release-cycle).
-It's highly recommended to include the Code Quality template as shown in the
-[example configuration](#example-configuration), which uses the new versioning scheme.
-If not using the template, the `SP_VERSION` variable can be hardcoded to use the
-new image versions:

-```yaml
