Get a list of all the files in a directory (recursive)

I'm trying to get (not print, that's easy) the list of files in a directory and its sub directories.

I've tried:

def folder = "C:\\DevEnv\\Projects\\Generic";
def baseDir = new File(folder);
files = baseDir.listFiles();

I only get the directories. I've also tried:

def files = [];

def processFileClosure = {
        println "working on ${it.canonicalPath}: "
        files.add (it.canonicalPath);
    }

baseDir.eachFileRecurse(FileType.FILES, processFileClosure);

But "files" is not recognized in the scope of the closure.

How do I get the list?

This is what I came up with for a gradle build script:

task doLast {
    ext.FindFile = { list, curPath ->
        def files = file(curPath).listFiles().sort()

        files.each {  File file ->

            if (file.isFile()) {
                list << file
            }
            else {
                list << file  // If you want the directories in the list

                list = FindFile( list, file.path) 
            }
        }
        return list
    }

    def list = []
    def theFile = FindFile(list, "${project.projectDir}")

    list.each {
        println it.path
    }
}
