我试图通过本教程Apache Ant - 教程来学习 apache ant
但是在我逐步创建构建文件并运行它之后，它会抛出：
compile:
[javac] /home/nazar_art/workspace/de.vogella.build.ant.first/src/test/build.xml:27: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
jar:
[jar] Building MANIFEST-only jar: /home/nazar_art/workspace/de.vogella.build.ant.first/src/test/dist/de.vogella.build.test.ant.jar
docs:
BUILD FAILED
/home/nazar_art/workspace/de.vogella.build.ant.first/src/test/build.xml:34: No source files and no packages have been specified.
我不明白为什么会这样？我使用 Ubuntu 12.04 操作系统和 Eclipse Indigo。
构建.xml：
<?xml version="1.0"?>
<project name="Ant-Test" default="main" basedir=".">
<!-- Sets variables which can later be used. -->
<!-- The value of a property is accessed via ${} -->
<property name="src.dir" location="src" />

代码部分：
package math;
public class MyMath {
public int multi(int number1, int number2) {
return number1 * number2;
}
}
package test;
import math.MyMath;
public class Main {
public static void main(String[] args) {
MyMath math = new MyMath();
System.out.println("Result is: " + math.multi(5, 10));
}
}
- 如何解决这个麻烦？
