大数据-hadoop-Ant使用

Ant

使用Ant打包Jar

<?xml version="1.0" encoding="utf-8"?>
<!--
	maven项目使用ant打包步骤
		1.命令行执行mvn dependency:copy-dependencies
			把依赖的jar copy到${project.path}/target/dependency/目录下.可以很容易的利用好Ant.
		2.ant OR ant javadoc 打包程序或者生成文档
			打包的程序一般在:${project.path}/target/dist/${version}/
			JavaDoc文档一般在${project.path}/target/ant/javadoc/
