Automatic clean for a Copy task deletes content unrelated to it

What makes it worse is that it does not even seem possible to override the outputs of the copy task with the files being copied. In my case, even with something like

task unzipDependencies(type: Copy) {
    into '.'
      FileTree output
    configurations.compile.resolvedConfiguration.resolvedArtifacts.each { artifact ->
        if (artifact.file.name.endsWith('.zip')) {
            FileTree contents = zipTree(artifact.file)
            from contents
            if (output == null) {
                output = contents
            } else {
                output += contents
            }
        }
    }
    outputs.files output
}

cleanUnzipDependencies would still delete everything under ‘.’.
