What restrictions are there when using a Bamboo Starter License?
With a Bamboo Starter License, you are allowed Unlimited local agents and 10 Jobs. A Job is a single build unit within a Plan. One or more Jobs can be organized into one or more Stages. Given a 10 Job limit, you may distribute your Jobs between up to 10 Plans - for example, one Job per Plan or all 10 Jobs within one Plan. There is no limit on the number of times a Plan is built/executed.
Please note that use of the Plan Branches feature has a multiplicative effect on the number of jobs configured, and therefore, an effect on the 10-job cap. For example, a plan with two jobs that is building against a total of three branches (the plan's original branch, plus two additional branches) will contribute 6 jobs toward the limit.
