只是把Apache Ant User Manual-HelloWorld with Ant裡的範例重新記錄下來而已。
有樣版以後寫起ant會比較方便:)
HelloWorld Sample
1.新增一個HelloWord專案
2.新增一個bigd.HelloWorld.java package
Java Resources:src -> New ->Class
3.HelloWorld.java Sample
package bigd;
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Bigd Say:Hello World");
}
}
4.加入build.xml
<project name="HelloWorld" basedir="." default="main">
<property name="src.dir" value="src"/>
<property name="build.dir" value="build"/>
<property name="classes.dir" value="${build.dir}/classes"/>
<property name="jar.dir" value="${build.dir}/jar"/>
<property name="main-class" value="oata.HelloWorld"/>
<target name="clean">
<delete dir="${build.dir}"/>
</target>
<target name="compile">
<mkdir dir="${classes.dir}"/>
<javac srcdir="${src.dir}" destdir="${classes.dir}"/>
</target>
<target name="jar" depends="compile">
<mkdir dir="${jar.dir}"/>
<jar destfile="${jar.dir}/${ant.project.name}.jar" basedir="${classes.dir}">
<manifest>
<attribute name="Main-Class" value="${main-class}"/>
</manifest>
</jar>
</target>
<target name="run" depends="jar">
<java jar="${jar.dir}/${ant.project.name}.jar" fork="true"/>
</target>
<target name="clean-build" depends="clean,jar"/>
<target name="main" depends="clean,run"/>
</project>
5.Run As -> Ant.Build
當HelloWorld.java引用外部的jar的情況
1.修改先前的HelloWorld.java Sample
package bigd;
import org.apache.log4j.Logger;
import org.apache.log4j.BasicConfigurator;
public class HelloWorld {
static Logger logger = Logger.getLogger(HelloWorld.class);
public static void main(String[] args) {
BasicConfigurator.configure();
logger.info("Hello World"); // the old SysO-statement
}
}
2.將log4j-1.2.16.jar加入專案內的WebContent/WEB-INF/lib
3.修改先前的build.xml,請注意你引用的lib路徑,本例是在WebContent/WEB-INF/lib之下。
<project name="HelloWorld" basedir="." default="main">
專案內用的libs目錄
<property name="lib.dir" value="WebContent/WEB-INF/lib"/>
<path id="classpath">
<fileset dir="${lib.dir}" includes="**/*.jar"/>
</path>
<property name="src.dir" value="src"/>
<property name="build.dir" value="build"/>
<property name="classes.dir" value="${build.dir}/classes"/>
<property name="jar.dir" value="${build.dir}/jar"/>
<property name="main-class" value="bigd.HelloWorld"/>
<target name="clean">
<delete dir="${build.dir}"/>
</target>
<target name="compile">
<mkdir dir="${classes.dir}"/>
<javac srcdir="${src.dir}" destdir="${classes.dir}" classpathref="classpath"/>
</target>
<target name="run" depends="jar">
<java fork="true" classname="${main-class}">
<classpath>
<path refid="classpath"/>
<path location="${jar.dir}/${ant.project.name}.jar"/>
</classpath>
</java>
</target>
<target name="jar" depends="compile">
<mkdir dir="${jar.dir}"/>
<jar destfile="${jar.dir}/${ant.project.name}.jar" basedir="${classes.dir}">
<manifest>
<attribute name="Main-Class" value="${main-class}"/>
</manifest>
</jar>
</target>
<target name="clean-build" depends="clean,jar"/>
<target name="main" depends="clean,run"/>
</project>
4.執行build.xml你可以看到以下結果
Buildfile: /home/owen/workspace/HelloWorld/build.xml
clean:
[delete] Deleting directory /home/owen/workspace/HelloWorld/build
compile:
[mkdir] Created dir: /home/owen/workspace/HelloWorld/build/classes
[javac] Compiling 1 source file to /home/owen/workspace/HelloWorld/build/classes
jar:
[mkdir] Created dir: /home/owen/workspace/HelloWorld/build/jar
[jar] Building jar: /home/owen/workspace/HelloWorld/build/jar/HelloWorld.jar
run:
[java] 0 [main] INFO bigd.HelloWorld - Hello World
main:
BUILD SUCCESSFUL
