Ant项目示例

4. ant示例

4.1 新建目录编译文件

<?xml version="1.0" encoding="utf-8"?>
<project name="myAntProject" basedir="." default="package">
    <property name="compile" value="compile"></property>
    <target name="init"></target>
    <target name="preprocess" depends="init">
        <mkdir dir="${compile}"/>
    </target>
    <target name="complie" depends="init,preprocess"></target>
    <target name="package" depends="complie"></target>
    <target name="myCompile" depends="preprocess">
        <javac srcdir="src" destdir="${compile}"></javac>
    </target>
</project>

4.2 打包文件

<?xml version="1.0" encoding="utf-8"?>
<project name="myAntProject" basedir="." default="package">
    <property name="compile" value="compile"></property>
    <property name="dist" value="dist"></property>
    <target name="init"></target>
    <target name="preprocess" depends="init">
        <mkdir dir="${compile}"/>
        <mkdir dir="${dist}"/>
    </target>
    <target name="complie" depends="init,preprocess"></target>
    <target name="package" depends="complie"></target>
    <target name="myCompile" depends="preprocess">
        <javac srcdir="src" destdir="${compile}"></javac>
    </target>
    <target name="dist" depends="myCompile">
        <jar destfile="${dist}/package.jar" basedir="${compile}"></jar>
    </target>
</project>

jar包中会附带生成jar文件的ant的信息META-INF/MANIFEST.MF
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.9.6
Created-By: 1.8.0_101-b13 (Oracle Corporation)

4.3 生成图形界面的jar文件

<?xml version="1.0" encoding="utf-8"?>
<project name="myAntProject" basedir="." default="package">
    <property name="compile" value="compile"></property>
    <property name="dist" value="dist"></property>
    <target name="init"></target>
    <target name="preprocess" depends="init">
        <mkdir dir="${compile}"/>
        <mkdir dir="${dist}"/>
    </target>
    <target name="complie" depends="init,preprocess"></target>
    <target name="package" depends="complie"></target>
    <target name="myCompile" depends="preprocess">
        <javac srcdir="src" destdir="${compile}"></javac>
    </target>
    <target name="dist" depends="myCompile">
        <jar destfile="${dist}/package.jar" basedir="${compile}">
            <manifest>
                <attribute name="Built-by" value="${user.name}"/>
                <attribute name="Main-Class" value="com.test.Test01"/>
            </manifest>
        </jar>
    </target>
</project>

通过mainfest定义构建内容
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.9.6
Created-By: 1.8.0_101-b13 (Oracle Corporation)
Built-by: chenchen
Main-Class: com.test.Test01

4.4 编译定义时间戳

<target name="dist" depends="myCompile">
    <tstamp></tstamp>
    <jar destfile="${dist}/package-${DSTAMP}.jar" basedir="${compile}">
        <manifest>
            <attribute name="Built-by" value="${user.name}"/>
            <attribute name="Main-Class" value="com.test.Test01"/>
        </manifest>
    </jar>
</target>

4.5 删除文件

<target name="deleteFile">
    <delete file="${dist}/package-20181201.jar"></delete>
</target>

4.6 拷贝文件

<target name="copyFile">
    <copy file="src/com/test/Test01.java" tofile="C:/Users/chenchen/Desktop/Test.java"></copy>
</target>

4.7 移动文件

<target name="moveFile">
    <move file="C:/Users/chenchen/Desktop/Test.java" todir="d:/"></move>
</target>

4.8 压缩文件

<target name="compress" depends="myCompile">
    <zip destfile="${dist}/package.zip" basedir="${compile}"></zip>
</target>

4.9 解压缩文件

<target name="uncompress" depends="compress">
    <unzip dest="${dist}" src="${dist}/package.zip"></unzip>
</target>

4.10 ant集成cvs

<property name="cvsRoot" value=":pserver:username:password@localhost:c:\cvs"></property>
<property name="destLocation" value="C:/Users/chenchen/Desktop/"></property>
<target name="preprocess" depends="init">
    <mkdir dir="${destLocation}"/>
</target>
<target name="cvs" depends="preprocess">
        <cvs cvsroot="${cvsRoot}" package="project01" command="checkout" dest="${destLocation}"></cvs>
</target>

4.11 替换内容

summary="on"属性显示替换信息

<target name="replaceOperation">
<replace file="input.txt" token="how" value="what" summary="on"></replace>
</target>

4.12 拷贝文件

<include name="*.java"/>单层目录文件
<include name="**/*.java"/>所有目录文件

<property name="src" value="src"></property>
<target name="copy2">
    <copy todir="${dist}">
        <fileset dir="${src}">
            <include name="**/*.java"/>
        </fileset>
    </copy>
</target>

5. 自定义ant

1. 导入ant.jar

2. 编写自定义文件，实现Task接口
package com.tool;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.ListIterator;
import org.apache.tools.ant.BuildException;
import org.apache.tools.ant.Task;
public class FileSorter extends Task {
    private File srcFile;
    private File destFile;
    public File getSrcFile() {
        return srcFile;
    }
    public void setSrcFile(File srcFile) {
        this.srcFile = srcFile;
    }
    public File getDestFile() {
        return destFile;
    }
    public void setDestFile(File destFile) {
        this.destFile = destFile;
    }
    @Override
    public void execute() throws BuildException {
        try {
            BufferedReader fromFile = new BufferedReader(new FileReader(srcFile));
            BufferedWriter toFile = new BufferedWriter(new FileWriter(destFile));
            List<String> list = new ArrayList<>();
            String line = fromFile.readLine();
            while (line != null) {
                list.add(line);
                line = fromFile.readLine();
            }
            Collections.sort(list);
            for (ListIterator<String> li = list.listIterator(); li.hasNext();) {
                String str = li.next();
                toFile.write(str);
                toFile.newLine();
            }
            fromFile.close();
            toFile.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

3. input.txt文件
hello world
what are you
what old are you
what do you do
abc
test

4. build.xml文件
<taskdef name="myFileSorterExample" classname="com.tool.FileSorter" classpath="bin">
</taskdef>
<target name="myFileSorter">
    <myFileSorterExample srcFile="input.txt" destFile="output.txt"></myFileSorterExample>
</target>

5. 运行结果output.txt
abc
hello world
test
what are you
what do you do
what old are you
