[bamboo server spec yaml] How to find out the requirements?

[Bill Wang]

In introduction document for bamboo spec yaml, the sample gives the usage about requirements

        requirements:
            - system.builder.mvn3.Maven 3
            - linux 

So my questions, how can I found out the available requirements (the correct name or descriptions)?

For example, I'd like to mention for a requirements of make or java version, how to find out the right name.
