将下载的 Ivy 包，进行示例程序 hello-ivy 编译的时候出现下面的错误：[code]D:\apache-ivy-2.2.0\src\example\hello-ivy>ant
Buildfile: D:\apache-ivy-2.2.0\src\example\hello-ivy\build.xml
resolve:
BUILD FAILED
D:\apache-ivy-2.2.0\src\example\hello-ivy\build.xml:38: Problem: failed to create task or

Cause: The name is undefined.
Action: Check the spelling.

This appears to be an antlib declaration.

只需要简单的将你下载的 Ivy 包中的 ivy-2.2.0.jar 文件拷贝到你 ant 的 lib 目录下就可以了。
这里不同的版本会有不同的包的名字。
当你完成这个操作后，重新执行 ant 命令，边可以正常完成编译了。
编译输出内容如下：[code]D:\apache-ivy-2.2.0\src\example\hello-ivy>ant
