通过Gradle FileTree.include删除目录 [英] Deleting directories via gradle FileTree.include

问题描述

我想说：

  clean.delete（fileTree（a）{
 includesubdir /
包含aFile
}）
  

删除目录子目录和文件aFile。但是subdir不会被删除。我可以明确地列出它：

  clean.delete（a / subdir）
  

但这比我想要的更重复。可以fileTree.include做这个工作吗？

到目前为止，我已经拿出：

  [subdir，
aFile，
 ... 
] .each {it  - > 
 clean.delete（a / $ it）
} 
  

但是这只是有点尴尬。

解决方案

恐怕这是不可能的。在Gradle论坛上查看此讨论。讨论导致这个问题。

一个简单的测试显示

 任务makeDir<< {
 ['a'，'a / subdir']。each {new File（it）.mkdirs（）} 
新文件（'a / aFile'）。createNewFile（）
 
 def tree = fileTree（'a'）{
 include'subdir /'
 include'aFile'
} 
 
 tree.each {档案文件 - > 
 println file 
 
 
  

仅打印文件并而不是目录，因为目录被遍历。您的解决方案很好，但您可以保存一些字符：

  [subdir，
aFile，
 ... 
] .each {clean.delete（a / $ it）} 
  

因此，fileTree仅适用于目录树中的文件，而不适用于目录。

I want to say:

clean.delete(fileTree("a") {
   include "subdir/"
   include "aFile"
})

to delete the directory "subdir" and the file "aFile". But "subdir" is not deleted. I could list it explicitly:

clean.delete("a/subdir")

but that is more repetitious than I would like. Can fileTree.include be made to do this job?

So far I have come up with:

[ "subdir",
  "aFile",
  ...
].each { it -> 
   clean.delete("a/$it") 
}

but that is just a bit awkward.

解决方案

I am afraid this is not possible. See this discussion on the gradle forum. The discussion lead to this issue.

A simple test shows

task makeDir << {
    ['a', 'a/subdir'].each { new File(it).mkdirs() }
    new File('a/aFile').createNewFile()

    def tree = fileTree('a') {
        include 'subdir/'
        include 'aFile'
    }

    tree.each {File file ->
        println file
    }
}

prints only the file and not the directory, as the directory is traversed. Your solution is good but you could save some chars:

[ "subdir",
  "aFile",
  ...
].each { clean.delete("a/$it") }

So fileTree is just for files in a directory tree and not for directories.
