A groovy directory traverse that excludes given dirs. Change the last closure to do something interesting instead of printing the dir name

dir_traverse.groovy

import groovy.io.FileType
import groovy.io.FileVisitResult

final excludedDirs = ['.svn', '.git', '.hg', '.idea', 'node_modules', '.gradle', 'build']
int count = 0

new File(root).traverse(
        type                : FileType.DIRECTORIES,
        preDir              : { if (it.name in excludedDirs) return FileVisitResult.SKIP_SUBTREE }, // excludes children of excluded dirs
        excludeNameFilter   : { it in excludedDirs }, // excludes the excluded dirs as well
//        nameFilter          : { it == 'settings.gradle'} // matched only given names
) {println it; count++}

println "count:$count"
