That might be intentionally not supported. Jenkins is a class-platform product, and if some platforms don't allow environment variables with empty values, this could cause inconsistent behavior.

It is often considered as an issue to have empty values for environment variables. Which is exactly your use case?

My "Properties Content" section looks like this: materialize_version=v1.0 keyring_location= workspace_build_type=clean I want the keyring_location variable set, but empty (null). In bash, these are two different conditions. However, it looks as though the plugin is not setting the variable at all, rather than setting it to null. This feels like a bug. If I put the "keyring_location=" in the build section shell commands, it correct sets it to null as I require. Is there a way to do this in the "Properties Content" section?
