Ant使用总结

安装Ant： 
假设安装在d盘：D:\apache-ant-1.8.4   ，直接解压就行。 
设置ANT_HOME系统变量和PATH系统变量： 

路径设置代码

1. set ANT_HOME= D:\apache-ant-1.8.4
2. set PATH=%ANT_HOME%\bin   

调整ant的运行时最大占用内存：

在ant.bat文件的REM only runs on WinNT下，加上一句：

set ANT_OPTS=-Xmx1024m

指定执行ant的文件

ant -f build.xml

指定target

<?xml version="1.0" encoding="UTF-8"?>
<project name='blizzard' default="main" basedir=".">
    <property environment="env"/>
    <property name="subproject.target" value="main"/>
    <target name="main" depends="game-common,gate,game" description="mini build">
    <tstamp>
        <format property="build.datetime" pattern="MM/dd/yyyy hh:mm:ss aa" />
    </tstamp>
        <echo>ant main target completed on ${build.datetime} </echo>
    </target>
    <target name="game-common" description="build the game-common">
        <ant inheritAll="false" antfile="${basedir}/game-common/build.xml" target="${subproject.target}"/>
    </target>
    <target name="game" description="build the game">
        <ant inheritAll="false" antfile="${basedir}/game/build.xml" target="${subproject.target}"/>
    </target>
    <target name="gate" description="build the gate">
        <ant inheritAll="false" antfile="${basedir}/gate/build.xml" target="${subproject.target}"/>
    </target>
     <target name="start" description="start all the services">
        <ant inheritAll="false" antfile="${basedir}/gate/build.xml" target="start" />
        <ant inheritAll="false" antfile="${basedir}/game/build.xml" target="start" />
    </target>

    <target name="stop" description="stop all the services">
        <ant inheritAll="false" antfile="${basedir}/gate/build.xml" target="stop" />
        <ant inheritAll="false" antfile="${basedir}/game/build.xml" target="stop" />
    </target>
</project>

ant game

ant  game-common game start

编译web工程时，会提示找不到三个包，最好这些JAR放到ant的lib目录下

apache-ant-1.9.2\lib

jsp-api.jar"
servlet-api.jar
el-api.jar"

这些在tomcat的lib里能找到

如何提取版本信息？

<target name="version" description="Use SVN to get the current revision" unless="disable-svnCheck">
    <taskdef resource="net/sf/antcontrib/antcontrib.properties"/>
    <property file="${basedir}/version.properties" />
    <tstamp>
      <format property="versionTime" pattern="yyyyMMdd" />
    </tstamp>
    <if>
    <equals arg1="${date}" arg2="${versionTime}"/>
    <then>
    <math result="packageTimes" operand1="${release}" operation="+" operand2="1" datatype="int"/>
      <propertyfile file="${basedir}/version.properties" comment="version properties file">
          <entry  key="date" type="date" value="now" pattern="yyyyMMdd"/>
          <entry  key="release" type="int" value="1" operation="+"/>
      </propertyfile>
    </then>
    <else>
      <property name="packageTimes" value="1" />
      <propertyfile file="${basedir}/version.properties" comment="version properties file">
          <entry  key="date" type="date" value="now" pattern="yyyyMMdd"/>
          <entry  key="release" type="int" value="1" operation="="/>
      </propertyfile>
    </else>
    </if>
    <exec executable="svn" logerror="true" outputproperty="svn.exec.result" failonerror="true" failifexecutionfails="true">
      <arg line="up" />
    </exec>
    <propertyregex property="svn.revision" input="${svn.exec.result}" regexp="(\d+)" select="\1" casesensitive="false" />
    <propertyregex property="branch" input="${basedir}" regexp="([^\${file.separator}]+$)" select="\1" casesensitive="false" />
    <echo level="info" message="svn.revision=${svn.revision},branch=${branch},version=S${versionTime}R${packageTimes}" />
  </target>

如何使用复杂的逻辑和运算

Ant-contrib 为 Ant 提供了与通常所使用的编程语言功能相同的 <if> 、 <for>、<switch>等逻辑判断任务，支持对字符串的排序<sortlist>任务，甚至还支持常见的数学运算，如加、减、乘、除、求余等功能。在构建过程中灵活运用这两个扩展包，将大大增强 Ant 的可编程性，这其实就是一种基于 XML 脚本的编程。
