- Users can traverse all the pods that are in the scheduler and waiting in the permit stage through method `IterateOverWaitingPods`. In other words,  all waitingPods in scheduler can be obtained from any profiles. Before this commit, each profile could only obtain waitingPods...

* 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)

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:
