Get plan configuration from job configuration

Hello, i am currently developing a plugin that sets additional configuration for a plan, and for each of its jobs, via the AdditionalBuildConfigurationPlugin.

I currently have two AdditionalBuildConfirsgurationPlugin modules, one for the plan and one for the job, with different configurations. In the plan configuration, i let the user define a series of parameters, let’s say for the sake of simplicity a given string, s

  • In the plan level configuration (miscellaneous tab) the user configures via a textbox a field “test”.

How can i recover this configured field (once saved) from the AdditionalBuildConfigurationPlugin that i am applying to the job?

Thank you very much!
PS: If you need additional information i can provide it!
