Error passing closure to function in Groovy

I have written a closure within a Groovy script to copy files, and then I pass that closure to eachFileMatch(regex, closure) to copy all files that match the given regex. When I prototyped it in the Groovy Console everything worked just fine but now when I run it in Eclipse I get the following error:

groovy.lang.MissingMethodException: No signature of method: java.lang.String.eachFileMatch() is applicable for argument types: (java.util.regex.Pattern, file_copy$_run_closure3)

Here is the closure and the call to eachFileMatch()

def fileCopyClosure = {

if(it.canRead()){
    def destFolder = new File("${outputDirectory}")
    if(!destFolder.exists()){
        println "Creating directory"
        destFolder.mkdir()
    }


    def desti = new File("${outputDirectory}\\${it.name}")
    output = desti.newOutputStream()
    it.eachByte(1024, write)
    output.close()

}
}
sourceDir.eachFileMatch(regex, fileCopyClosure)

Try new File(sourceDir).eachFileMatch(regex, fileCopyClosure)

from the exception, sourceDir is a String, not a File that you need for eachFileRecurse
