Providing override of custom plugin Zip task

I am developing a custom plugin which introduces a task for creating a zip file of things within the project which will then get uploaded into some other repository outside of gradle. By default I want to provide a default setup of things that should get included in the zip, but I also want to provide a way for this to be added to and/or overridden in a particular project.

This is what I have for my plugin:

class CustomPlugin implements Plugin<Project> {
 @Override
 void apply(Project project) {
  project.configure(project) {
   buildDir = file("${project.projectDir}/target")
     task(type: Zip, description: 'Builds artifacts.zip that gets exploded into a new asset', group: 'Asset Management', 'buildDistributionZip') {
    archiveName = 'artifacts.zip'
    from(buildDir) {
                                        include 'distributions/**'
     include 'docs/**'
     include 'libs/**'
     include 'reports/**'
     include 'test-results/**'
    }
   }
  }
 }
}

This works great for projects that don’t define their own buildDistributionZip {} block, or for projects that want to add onto what goes into the zip. My question is, what if a project wants to completely override/remove the defaults and configure its own?

For example I can do this in a project’s build.gradle:

buildDistributionZip {
 from 'src'
}

Which, in addition to the things from buildDir, would also add everything from $projectDir/src into the zip. What if I just wanted $projectDir/src in the zip file and not the things from buildDir?

Any takers on this?
