ANT问题！

Question

我也没好好看过,给你个例子吧!
build.xml
<project name="aaa" default="compile" basedir=".">  <property name="app.name"       value="SYS-001"/>
  <property name="deploy.home"    value="${project.home}/webapps/${app.name}"/>
  <property name="dist.home"      value="${deploy.home}"/>
  <property name="dist.src"       value="${app.name}.jar"/>
  <property name="dist.war"       value="${app.name}.war"/>
<!--
  <property name="javadoc.home"   value="${deploy.home}/javadoc"/>
-->  <target name="prepare">

Answer 1

目录直接加就可以了2。它自己知道检查，不用你操心ANT是很好的东西，慢慢体会给你一个例子<?xml version="1.0" encoding="gb2312"?><project name="EasyMessage" default="package" basedir="."> <property file="build.properties"/>

<path id="alloy.lib">
<fileset dir="${lib.dir}">
<include name="alloy.jar"/>
<include name="feels.jar"/>
</fileset>
</path>

<target name="prepare" description="初始化，生成目录">
<mkdir dir="${build.dir}"/>
<mkdir dir="${build.dir.classes}"/>
</target>

<target name="clean" description="清除目录">
<delete dir="${build.dir}"/>
</target>

<target name="compile" depends="prepare" description="编译">
<javac classpath="."
srcdir="${src.dir}"
destdir="${build.dir.classes}">
<classpath refid="alloy.lib"/>
</javac>
</target>

<target name = "package" depends = "compile" description="打包">
<jar jarfile = "${classes.package}"
basedir = "${build.dir.classes}"
includes = "soft/**">
<manifest>
<attribute name = "Main-Class" value = "${main.class}"/>
<attribute name = "Class-Path" value = "${runtime.path}"/>
</manifest>
</jar>
<jar jarfile = "${src.package}"
basedir = "${src.dir}"
includes = "soft/**">
</jar>
</target>

</project>

Answer 2

1. 假如目录已经搞定，就是将要加的目录放在basedir属性所指的目录下就可以了。
2. 我试了一下，根据class文件的时间属性，可以看出，即使没有改变原文件，还是重新编译了一遍，请问是不是要在build.xml中有所设置？如果工程很大，重复编译很费时间。
下面是我的build.xml：
<?xml version="1.0"?><project name="TestGui" default="dist" basedir=".">    <property name="src" location="src"/>
    <property name="build" location="build"/>
    <property name="dist"  location="dist"/>
    <property name="resource"  location="resource"/>    <target name="init">
        <mkdir dir="${build}"/>
    </target>
    
    <target name="compile" depends="init">
        <javac srcdir="${src}" destdir="${build}"/>
    </target>
    
    <target name="dist" depends="compile">
        <mkdir dir="${dist}/lib"/>
        
        <jar jarfile="${dist}/lib/AntTest-${DSTAMP}.jar"
                basedir="${build}">
            <manifest>
<attribute name = "Main-Class" value = "com.myCompany.myPackage.AntTest"/>
    </manifest>
        </jar>
        </target>
    
    <target name="clean">
        <delete dir="${build}"/>
        <delete dir="${dist}/lib"/>
    </target>
</project>
