Groovy Question

Recursive listing of all files matching a certain filetype in Groovy

I am trying to recursively list all files that match a particular file type in Groovy. This example almost does it. However, it does not list the files in the root folder. Is there a way to modify this to list files in the root folder? Or, is there a different way to do it?

Answer

This should solve your problem:

import static groovy.io.FileType.FILES

new File('.').eachFileRecurse(FILES) {
    if(it.name.endsWith('.groovy')) {
        println it
    }
}

eachFileRecurse takes an enum FileType that specifies that you are only interested in files. The rest of the problem is easily solved by filtering on the name of the file. Might be worth mentioning that eachFileRecurse normally recurses over both files and folders while eachDirRecurse only finds folders.
