* filter them (using link:{javadocPath}/org/gradle/api/file/FileTree.html#matching-org.gradle.api.Action-[FileTree.matching(org.gradle.api.Action)] and Ant-style patterns)
* merge them

You can also traverse file trees using the link:{javadocPath}/org/gradle/api/file/FileTree.html#visit-org.gradle.api.Action-[FileTree.visit(org.gradle.api.Action)] method.
All of these techniques are demonstrated in the following example:

			Prefix: "/",

		g.Expect(routes[1].Action.(*envoyroute.Route_Route).Route.ClusterNotFoundResponseCode).
