ansible-lint: "WARNING Unable to load module ... for options validation"

[irozet12]

Summary

The issue is found with ansible-lint, but I suggest the fix in ansible-compat, that is why I report it here. Similar issue: #2861

ansible-lint installs required collections, and then can't load modules from them, the following warnings are printed:

WARNING  Unable to load module cloud.terraform.terraform at main.yml:34 for options validation
WARNING  Unable to resolve FQCN for module cloud.terraform.terraform

When we run ansible-lint second time, when required collections are already installed, the warnings do not appear

Issue Type

• Bug Report

OS / ENVIRONMENT

python -c "import ansible_compat; print(ansible_compat.__version__)"
24.9.1

• ansible installation method: one of source, pip, OS package
  pip
• ansible-compat installation method: one of source, pip, OS package
  pip

STEPS TO REPRODUCE

Run ansible-lint on a project which has a requirement for a collection and uses a module from the collection in a playbook. The required collection must not be installed on the node before running ansible-lint

For example, add cloud.terraform to requiremenmts.yml, and cloud.terraform.terraform module to a plybook in the project.

Playbook:

    - name: Bring the infrastructure to state '{{ state }}'
      cloud.terraform.terraform:
        project_path: terraform/
        state: "{{ state }}"

requirements.yml:

---
collections:
  - name: cloud.terraform
    version: 2.0.0

Run ansible-lint in the project directory.

Desired Behavior

Module cloud.terraform.terraform should be successfully loaded on the fist run

Actual Behavior

'Unable to load module' warnings appear
