ant学习笔记2

ant简明教程，其中包括if，unless，copy，move，delete，mkdir，echo，property，javac，jar，war（使用war命令打包JavaEE项目 ）实现命令的介绍。

ant的常见数据类型，其中涉及到的有：

<arg/>
<env/>
<filelist/>
<fileset/>
<patternset></patternset>
<filterset/>
<path></path>
<mapper></mapper>

其他的数据类型包含在org.apache.tool.ant.types包中

而在hadoop的build.xml中还差的命令有如下：,要想知道其中的含义，需查看ant的各种默认命令，或者官网doc。以下是我将要要学习的，如果有读者恰巧看到，以下就越过吧。太复杂了，我还没疏通。
