          　　ant是jakarta一個非常好的OpenSource子項目，是基于java的編譯工具。下面簡單介紹一下在linux環(huán)境中如何安裝ant：
          

          　　1.下載
          
　　從 http://ant.apache.org/bindownload.cgi
          
可以下載最新的tar包：apache-ant-1.6.2.tar.gz，如果是windows環(huán)境則是zip文件，解壓后，在系統(tǒng)環(huán)境變量里設(shè)置
          
ANT_HOME為f:\project\tools\apache-ant-1.6.2，并將f:\project\tools\apache-ant
          
-1.6.2\bin目錄添加到classpath中，然后就可以使用了
          

          　　2.安裝，解壓到/usr/local下
          
> tar zxpvf apache-ant-1.6.2.tar.gz
          
> ln -s apache-ant-1.6.2 ant
          

          　　3.設(shè)置環(huán)境
          
　　將ANT_HOME設(shè)置到當(dāng)前用戶的.bash_profile文件/home/admin/.bash_profile
          

          [admin@tangtang home]$ su - admin
          
[admin@tangtang home]$ vi .bash_profile
          
export ANT_HOME=/usr/local/ant
          
export PATH=/usr/local/ant/bin:$PATH
          

          　　如果是windows環(huán)境，需要設(shè)置%ANT_HOME%，并把%ANT_HOME%\bin目錄全路徑加入到%path%中
          

          　　4.測試
          
　　用ant命令測試運(yùn)行情況
          
[admin@tangtang home]$ ant 
          
Buildfile: build.xml does not exist!
          
Build failed
          

          [admin@tangtang home]$ ant -version
          
Apache Ant version 1.6.2 compiled on July 16 2004
          

          　　若出現(xiàn)這樣的錯誤：Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tools/ant/launch/Launcher 
          
　　這是linux系統(tǒng)默認(rèn)安裝了一些ant的lib，修改 /etc/ant.conf中 ANT_HOME=/usr/share/ant 為你正確安裝ant的地址，如 /usr/local/ant
          

          　　5、build腳本
          
　　如果是在linux環(huán)境中，下面是build腳本的一個范例：
          

          #build腳本
          
#! /bin/sh
          
# 進(jìn)入到上級目錄
          
cd `dirname $0`/..
          
# 獲取當(dāng)前目錄為PROJECT_HOME
          
PROJECT_HOME=`pwd`
          
# 設(shè)置JAVA_HOME
          
export JAVA_HOME=/usr/cyber/java
          
# 得到CLASSPATH
          
CLASSPATH1=$CLASSPATH
          
# 添加CLASSPATH
          
CLASSPATH=${PROJECT_HOME}\webapps\WEB-INF\conf:${PROJECT_HOME}\webapps\WEB-INF\classes:$CLASSPATH
          
# ant build，-buildfile 參數(shù)，是使用自定義的build.xml文件，$@是參數(shù)數(shù)組
          
/usr/local/ant/bin/ant -buildfile ${PROJECT_HOME}/build/build.xml "$@"
          
# build腳本結(jié)束
          

          

          　　如果是在windows環(huán)境中，下面是build.bat腳本的一個范例：
          

          # build.bat 
          
# 關(guān)閉echo顯示
          
@echo off
          
# 設(shè)置%JAVA_HOME%
          
if "%JAVA_HOME%"=="" set JAVA_HOME=f:\tools\java
          
# 設(shè)置%ANT_HOME%
          
if "%ANT_HOME%"==""  set ANT_HOME=f:\tools\ant
          
# 設(shè)置PROJECT_HOME
          
set PROJECT_HOME = %CD%\..
          
set CLASSPATH_BAK=%CLASSPATH%
          
set CLASSPATH=
          
# 執(zhí)行build
          
%ANT_HOME%\bin\ant.bat -buildfile ..\build\build.xml %1 %2 %3 %4 %5 %6 %7 %8 %9
          

          

          　　6、build配置文件
          
　　在${PROJECT_HOME}/build目錄下面，需要定義兩個文件，一個是build.properties，一個是build.xml
          
　　build.properties文件定義了build的一些常量
          

          # build.properties
          
project        = tangtang
          
version        = 1.1.1
          
# 采用classic編譯，即采用ant編譯
          
build.compiler = classic
          
# 采用jikes編譯
          
#build.compiler = jikes
          

          
year           = 2004
          
debug          = on
          
optimize       = on
          
deprecation    = on
          

          
os             = linux
          
author         = tangtang
          
email          = syvin_tom@hotmail.com
          
url            = www.tangtang.org 
          
company        = tangtang.org
          

          
build.xml文件是ant編譯的主要配置文件，ant功能強(qiáng)大，需要通過相應(yīng)的配置項來表現(xiàn)。
