Summary

After a plan that produces a Shared Artifact is deleted, any plan that consumes that artifact fails. Although this is expected, disabling the Artifact Download task should allow the plan to run.

Steps to Reproduce

1. Create a Plan Throwaway Artifact that produces a Shared Artifact
2. Create a second Plan Artifact Test that consumes the Shared Artifact
3. Run the Throwaway Artifact Plan to produce the artifact
4. Run Artifact Test to successfully consume the Artifact
5. Disable the Artifact Download task in Artifact Test
6. Delete the Throwaway Artifact Plan
7. Re-run the Artifact Test Plan

Expected Results

Because the Artifact Download task is disabled, it should not affect the execution of the build plan.

Actual Results

The build does not start and the following exception is thrown in the atlassian-bamboo.log file and Build Result Summary page:
