Currently, variables in Bamboo have limited scope and are applicable only to specific plans.

The user should be able to specify global variables - applicable globally in Bamboo.

Has anyone been able to get the bamboo global variables to expand properly in the "System Environment Variables:" section of a builder? The global variables expand properly in the "target" section, but so far I have been unable to use them anywhere else. Are Bamboo global variables only usable in the "target" or "argument" section of a builder, or am I missing something?

It would be very useful if Bamboo global variables could be used anywhere, including when defining builder paths and jdk home directories in the Admin UI.
