几条总结：
一。在ant的构建文件中，根元素始终是：<project>
二。ant的概念模型：项目包含目标，目标包含任务，也就是把所有的目标放在目标中，即：所有的target，在project根标签下，且不要有其他东西在project根标签下。所有的执行过程，在targert标签中
三。在ant中，任何一个任务失败，会导致整个构建过程的终止
四。javac命令中依赖关系检查仅仅局限于在比对源文件与目标文件的日期上
我的代码：
HelloWorld.java//主类
package com.laolang.hello;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import com.laolang.stu.Student;public class HelloWorld { public static void main(String[] args) { BufferedReader br = new BufferedReader(new InputStreamReader( System.in)); Student stu = null; int id = 0; String name = null; int age = 0; String sex = null; try { System.out.print("输入学号："); id = Integer.parseInt(br.readLine()); System.out.print("输入姓名："); name = br.readLine(); System.out.print("输入年龄："); age = Integer.parseInt(br.readLine()); System.out.print("输入性别："); sex = br.readLine(); } catch (NumberFormatException | IOException e) { e.printStackTrace(); } stu = new Student(id, name, age, sex); System.out.println("student:"); System.out.println(stu); System.out.println("Hello World!"); System.out.println("小代码！"); }}
Student.java//学生类
package com.laolang.stu;public class Student { public Student() { super(); } public Student(int stuId, String stuName, int stuAge, String stuSex) { super(); this.stuId = stuId; this.stuName = stuName; this.stuAge = stuAge; this.stuSex = stuSex; } @Override public String toString() { return "Student [stuId=" + stuId + ", stuName=" + stuName + ", stuAge=" + stuAge + ", stuSex=" + stuSex + "]"; } public int getStuId() { return stuId; } public void setStuId(int stuId) { this.stuId = stuId; } public String getStuName() { return stuName; } public void setStuName(String stuName) { this.stuName = stuName; } public int getStuAge() { return stuAge; } public void setStuAge(int stuAge) { this.stuAge = stuAge; } public String getStuSex() { return stuSex; } public void setStuSex(String stuSex) { this.stuSex = stuSex; } private int stuId; private String stuName; private int stuAge; private String stuSex;}
build.xml
这是使用ant进行JAVA开发的第一个完整的例子
