Summary

A disabled artifact download task will still generate an exception and fail a build if it cannot find a successful plan result for the source plan of the shared artifact.

Steps to Reproduce

1. Create a plan TEST-PLAN1 which exports a shared artifact.
2. Create a plan TEST-PLAN2.
3. Add an Artifact Download task to TEST-PLAN2 which downloads the shared artifact from TEST-PLAN1.
4. Disable the artifact download task.
5. Build TEST-PLAN2 before building TEST-PLAN1.
6. Build fails with java.lang.IllegalArgumentException stating that it's "Unable to find at least one successful result for plan: TEST-PLAN1".

Expected Results

Build should succeed as the artifact download task is disabled.

Actual Results

The below exception is thrown in the atlassian-bamboo.log file:

java.lang.IllegalArgumentException: Unable to find at least one successful result for plan: TEST-PLAN1
	at com.atlassian.bamboo.plugins.artifact.ArtifactDownloaderRuntimeDataProvider.populateRuntimeTaskData(ArtifactDownloaderRuntimeDataProvider.java:90)

Workaround

Delete the artifact download task instead of disabling it or successfully complete a build of the source plan.
