如何在gradle中删除一个空目录（或递归地包含所有内容的目录）？ [英] How to delete an empty directory (or the directory with all contents recursively) in gradle?

问题描述

我无法弄清楚如何删除目录中的所有内容。

清理一个目录，我想删除其中的所有文件和目录：我想擦除里面的所有内容（文件和目录）。

我尝试过使用删除任务，但我无法弄清楚它也会删除目录而不仅仅是文件。

 任务deleteGraphicsAssets（类型：删除）{$ b $删除fileTree（'src'）.include（'** / *'）
} 
  

<

pre $ 任务deleteGraphicsAssets（类型：删除）{
删除fileTree（'src'）.include（' /'）
}


。

 任务deleteGraphicsAssets（类型：删除）{
删除fileTree（'src'）.include（'*'）
} 
  
 
 
 $ p 
 $ b

这很有效 - 但它看起来有点像破解。
 < code delete任务deleteGraphicsAssets（类型：删除）{
 def dirName =src
删除dirName 
 
 doLast {
 file（dirName）.mkdirs（ ）
} 
} 
  
我正在寻找类似的东西：
 任务删除GraphicsAssets（类型：删除）{
 deleteContentsOfDirectorysrc
} 
  
或
 任务deleteGraphicsAssets（类型：删除）{
 delete {dir：src，keepRoot：true} 
 
  
 
 
解决方案 
删除 src 目录及其所有内容： 
 
 
 任务deleteGraphicsAssets（类型：删除）{
删除src
} 
  
 
I can't figure out how to delete all contents of a directory. 


For cleaning out a directory, I want to remove all files and directories inside it: I want to wipe everything there is inside (files and directories).

I tried this with the delete task, but I can't figure out to make it also remove directories and not just files. I've tried different ways to specify the directories, but nothing works.
task deleteGraphicsAssets(type:Delete) {
    delete fileTree('src').include('**/*')
}
.
task deleteGraphicsAssets(type:Delete) {
    delete fileTree('src').include('/')
}
.
task deleteGraphicsAssets(type:Delete) {
    delete fileTree('src').include('*')
}
Any help appreciated!



Edit: 

This works - yet it seems a bit like a hack.
task deleteGraphicsAssets(type: Delete) {
    def dirName = "src"
    delete dirName

    doLast {
        file(dirName).mkdirs()
    }
}
I was looking for something like:
task deleteGraphicsAssets(type: Delete) {
    deleteContentsOfDirectory "src"
}
or 
task deleteGraphicsAssets(type: Delete) {
    delete {dir : "src", keepRoot : true }
}

解决方案
To delete the src directory and all its contents:
task deleteGraphicsAssets(type: Delete) {
    delete "src"
}
