How do I make a Bamboo build prefer its last build agent?

We have a Bamboo setup with about 30 build agents, and I have an incremental Gradle build.  An incremental build benefits greatly from being run on the same agent every time.  Is it possible to have make my build prefer its last build agent?

Workarounds:

(1) Create a Requirement so that my build only runs on a specific single agent.  But that only works so far:  Other builds will start on that agent, and my build will have to wait for those to finish.

(2) Create a Requirement so that my build only runs on a small set of agents. I will still lose a lot of the benefits of the incremental builds.

(3) Reserve a agent for my build only. My operations dept doesn't want to do this, as the agent will stay idle a lot.


So that leaves my question: is there a way for my build to prefer its last build agent, but switch to a different one if the last agent is busy?

We do not provide such functionality ATM. Agent - job matching is purely based on capabilities/requirements match.

By the way, is it possible to create a "matches" requirement?  All the agents have their own requirement keys:  agent01.example.com, agent02.example.com, ...  Is it possible to create a requirement that matches agent0[12].example.com?  Or is it only possible to match on key content?

We do not provide "matches" requirement. One more thing: there's "Agent dedication" feature in Bamboo 5.7. It allows you to dedicate given agent to running certain plans/jobs. Maybe this can help with your problem.
