Gradle tooling: webAppDir and additional task specific properties

Helping out with the netbeans plugin which is working pretty well ( I am trying to add plug-in specific folders (specifically war) to the project so that the web folder contents show up but it does not appear that this information makes it to the tooling apis. Is there any way from a org.gradle.tooling.model.GradleTask or a org.gradle.tooling.model.GradleProject to get this information? Specifically the webAppDir property. I’m sure for other project types some additional task specific information would be helpful as well.
