【转】ant 安装与配置
下载Apache Ant 1.8.4http://ant.apache.org/bindownload.cgi
一、解压ant安装包在D:\SWE下
二、环境变量配置
ANT_HOME D:\SWE\apache-ant-1.8.4 CLASSPATH ;%ANT_HOME%lib; PATH ;%ANT_HOME%bin;
三、测试是否安装成功
在cmd命令方式下输入:
ant -version
出现问题:
1)Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre6\lib
命令行敲ant命令后提示:“Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre6\lib”;ANT_HOME环境变量已经配置;
解决途径:将“C:\Program Files\Java\jdk1.6.0_16\lib”目录下的tools.jar文件拷贝到“C:\Program Files\Java\jre6\lib”目录下,重新运行命令ant,运行正常,问题解决。
2)在cmd命令中:输入ant,如果输出:
Buildfile:build.xml does not exist!
Build failed
说明ant安装成功。
四、运行第一个ant脚本
在D:\ant_home\apache-ant-1.8.1\bin\下面新建目录build,再在该目录下新建目录src
同时在src目录下新建HelloWorld.java
内容如下:
package test.ant; public class HelloWorld{ public static void main(String[] args){ System.out.println("Hello World"); } };
编写build.xml文件保存到D:\ant_home\apache-ant-1.8.1\bin\
内容如下:
<?xml version="1.0" encoding="UTF-8" ?> <project name="HelloWorld" default="run" basedir="."> <property name="src" value="build/src" /> <property name="dest" value="build/classes" /> <property name="hello_jar" value="hello.jar" /> <property name="name" value="HelloWorld" /> <property name="version" value="1.0" /> <property name="year" value="2010" /> <echo message="----------- ${name} ${version} [${year}] ------------" /> <target name="init"> <echo message="mkdir ${dest}"></echo> <mkdir dir="${dest}" /> </target> <target name="compile" depends="init" description="Compile Java code"> <javac srcdir="${src}" destdir="${dest}" includeantruntime="on"/> </target> <target name="build" depends="compile"> <jar jarfile="build/${hello_jar}" basedir="${dest}"/> </target> <target name="run" depends="build"> <java classname="test.ant.HelloWorld" classpath="build/${hello_jar}"/> </target> <target name="clean"> <delete dir="${dest}" /> <delete file="${hello_jar}" /> </target> </project>
运行:
Buildfile: D:\ant_home\apache-ant-1.8.1\bin\build.xml [echo] ----------- HelloWorld 1.0 [2010] ------------ init: [echo] mkdir build/classes compile: [javac] Compiling 1 source file to D:\ant_home\apache-ant-1.8.1\bin\build\classes build: [jar] Building jar: D:\ant_home\apache-ant-1.8.1\bin\build\hello.jar run: [java] Hello World BUILD SUCCESSFUL Total time: 1 second
检查在目录D:\ant_home\apache-ant-1.8.1\bin\build下生成hello.jar
