ANT使用

　　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)。
