Sometimes artifacts are not generated in builds, which is fine in some business cases. (some of the artifacts may be defined, others are not, depending on the release)

I still like to setup the deployment task 'Download Artifact' and just have it exit without failure if the artifact is missing. 

It would be great if we can check a box on the Download Artifact task configuration that says 'Fail on missing/empty artifact' (or the opposite)

The standard code is really close to having this feature.

The Artifact Downloader task is defined in 

com.atlassian.bamboo.plugins.artifact.ArtifactDownloaderTask.

This class has a property of 

final boolean failOnMissing = true;

which is always set to true.

If this is a configurable setting, that would help tremendously in our business case
