我知道我的构建.xml至少包含十个目标，但是当我运行ant -p时只显示两个目标：
$ ant -p build.xml
Buildfile: /home/nico/myproject/build.xml
Main targets:
clean clean
Default target: deploy
如何显示所有目标？
ant -p仅显示具有描述的目标。
要显示所有目标，请运行ant -p -v 。这将生成相当多的行，但在输出的末尾很容易找到完整的目标列表：

Default target: deploy
实际上，有一个简单的答案。"ant -p"命令将仅输出具有描述集的目标。例如：
<target name="target1" description="My first target">
我一直认为这是一种"控制"哪些目标是公开可见的方法，就像Java在方法上使用公共和私有等一样。
