Support defining parameters per-subproject

[ikstewa]

The current usage recommendation of this plugins shows all build parameters defined globally for the entire project.

We typically operate with a larger root project which multiple sub-projects. Each of those sub-projects may have parameters that are distinct to just that project.

Ideally we would like to apply the plugin to a sub-project, define the build parameters for that project, and reference from within the build file the parameters are defined in.

Is it possible to use this plugin to define build parameters per sub-project?
