 1. Ensure that the `GL_ASDF_TFLINT_VERSION` version for tflint is configured.
 1. Directories can be excluded from tflint using the `TFLINT_EXCLUDE_REGEX` variable. See the example below.
 1. The task will generate a [junit test output file](https://docs.gitlab.com/ee/ci/unit_test_reports.html) for any failed linter checks.
