Question

在使用ant作为构建工具的项目中，我具有以下简化的目录结构：

src/
   com/
      foo/
         bar/
            (some files)
         bar2/
            (some other files)

以及以下简化的ant脚本：

<project default="all">
    <target name="all">
        <delete dir="dst"/>
        <mkdir dir="dst"/>
        <copy todir="dst">
            <fileset dir="src" excludes="com/foo/bar/*"/>
        </copy>
    </target>
</project>

运行此ant脚本时，看到以下输出：

all:
   [delete] Deleting directory /home/grodriguez/workspace/_test/anttest/dst
    [mkdir] Created dir: /home/grodriguez/workspace/_test/anttest/dst
     [copy] Copying 1 file to /home/grodriguez/workspace/_test/anttest/dst
     [copy] Copied 4 empty directories to 1 empty directory under /home/grodriguez/workspace/_test/anttest/dst

问题：为什么蚂蚁报告正在复制“ 4个空目录”？那不应该是1个空目录（com / foo / bar）吗？

Answer 1

创建目录com/foo/bar意味着首先创建com，然后再创建com/foo-即三个目录。

我的Ant版本稍微冗长一些，并显示了每个创建操作：

$ ant -v
Apache Ant(TM) version 1.10.2 compiled on February 3 2018
... deleted for brevity ....
    [mkdir] Created dir: /stack/ant/dst
     [copy] com/foo/bar2/x.txt added as com/foo/bar2/x.txt doesn't exist.
     [copy]  omitted as /stack/ant/dst is up to date.
1    [copy] com added as com doesn't exist.
2    [copy] com/foo added as com/foo doesn't exist.
3    [copy] com/foo/bar added as com/foo/bar doesn't exist.
4    [copy] com/foo/bar2 added as com/foo/bar2 doesn't exist.
     [copy] Copying 1 file to /stack/ant/dst
     [copy] Copying /stack/ant/src/com/foo/bar2/x.txt to /stack/ant/dst/com/foo/bar2/x.txt
     [copy] Copied 4 empty directories to 1 empty directory under /stack/ant/dst

创建bar2时，它（显然）是空的，因此被计为4，即使在复制完成时它不是空的。

ant正在复制哪些“空目录”？
