I'd like to be able to run one plan but have multiple parameterized runs of that same plan. The key is here then I only have to modify one plan in one spot rather than cloning the existing plan and changing the parameters there. This is key for plans that have a high number of jobs. When you need to make changes to the tasks inside, if you had to clone your plan, then you need to edit multiple plans.

So I could then run my CI trunk plan against JDK 6 and JDK 7, for example, without cloning.

Certainly, allowing environment variables, capabilities and builders to be selected at the plan level would help this editing nightmare, but I think this is a great idea as part of the "run parameterized" concept.

It's almost a plan within plans.
