How do I delete a dirset of directories with Ant?
提问by jamesh
I want to delete all directories and subdirectories under a root directory that are contain "tmp" in their names. This should include any .svn files too. My first guess is to use
我想删除根目录下所有名称中包含“tmp”的目录和子目录。这也应该包括任何 .svn 文件。我的第一个猜测是使用
<delete>
<dirset dir="${root}">
<include name="**/*tmp*" />
</dirset>
</delete>
This does not seem to work as you can't nest a dirsetin a deletetag.
这似乎不起作用，因为您不能dirset在delete标签中嵌套 a 。
Is this a correct approach, or should I be doing something else?
这是一种正确的方法，还是我应该做其他事情？
- ant version == 1.6.5.
- java version == 1.6.0_04
- 蚂蚁版本 == 1.6.5。

Here's the answer that worked for me:
这是对我有用的答案：
<delete includeemptydirs="true">
<fileset dir="${root}" defaultexcludes="false">
<include name="**/*tmp*/**" />
</fileset>
</delete>
I had an added complication I needed to remove .svndirectories too. With defaultexcludes, .*files were being excluded, and so the empty directories weren't really empty, and so weren't getting removed.
我还有一个额外的复杂问题，我也需要删除.svn目录。使用defaultexcludes，.*文件被排除在外，因此空目录并不是真正的空目录，因此不会被删除。
The attribute includeemptydirs(thanks, flicken, XL-Plüschhase) enables the trailing **wildcard to match the an empty string.
属性includeemptydirs(thanks, flicken, XL-Plüschhase) 使尾随**通配符能够匹配空字符串。

try:
尝试：
<delete includeemptydirs="true">
<fileset dir="${root}">
<include name="**/*tmp*/*" />
</fileset>
</delete>
ThankYou flicken !

I just wanted to add that the part of the solution that worked for me was appending /**to the end of the include path. I tried the following to delete Eclipse .settings directories:
我只是想补充一点，对我有用的解决方案部分附加/**到包含路径的末尾。我尝试了以下删除 Eclipse .settings 目录：
<delete includeemptydirs="true">
<fileset dir="${basedir}" includes"**/.settings">
</delete>
but it did not work until I changed it to the following:
但直到我将其更改为以下内容后，它才起作用：
<delete includeemptydirs="true">
<fileset dir="${basedir}" includes"**/.settings/**">
</delete>
For some reason appending /**to the path deletes files in the matching directory, all files in all sub-directories, the sub-directories, and the matching directories. Appending /*only deletes files in the matching directory but will not delete the matching directory.
由于某种原因，追加/**到路径会删除匹配目录中的文件、所有子目录中的所有文件、子目录和匹配目录。追加/*只会删除匹配目录中的文件，但不会删除匹配目录。
