Groovy 中匹配特定文件类型的所有文件的递归列表 [英] Recursive listing of all files matching a certain filetype in Groovy

问题描述

我试图在 Groovy 中递归列出与特定文件类型匹配的所有文件.这个例子几乎做到了.但是，它不会列出根文件夹中的文件.有没有办法修改它以列出根文件夹中的文件?或者，有什么不同的方法吗?

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?

推荐答案

这应该可以解决您的问题:

This should solve your problem:

import static groovy.io.FileType.FILES

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

eachFileRecurse 采用枚举 FileType，指定您只对文件感兴趣.剩下的问题很容易通过过滤文件名来解决.可能值得一提的是，eachFileRecurse 通常对文件和文件夹进行递归，而 eachDirRecurse 只查找文件夹.

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.
