How to retrieve Jenkins build parameters using the Groovy API?

Question

I have a parameterized job that uses the Perforce plugin and would like to retrieve the build parameters/properties as well as the p4.change property that\'s set by the Perf

Regarding parameters:

See this answer first. To get a list of all the builds for a project (obtained as per that answer):

project.builds

When you find your particular build, you need to get all actions of type ParametersAction with build.getActions(hudson.model.ParametersAction). You then query the returned object for your specific parameters.

Regarding p4.change: I suspect that it is also stored as an action. In Jenkins Groovy console get all actions for a build that contains p4.change and examine them - it will give you an idea what to look for in your code.
