IndexOutOfBoundsException解压缩ear文件时出现异常

Question

这是我的部署脚本中的目标之一，它试图解压缩.ear文件。它失败，出现IndexOutOfBoundsException。

<target name="unzip">
        <unzip src="${project-name}.ear" dest="${unzip-destination}" />
</target>

如何找出导致此异常的原因？导致此异常的访问是哪个列表/数组？

听起来你有一个损坏的ear文件。我建议创建另一个zip文件，并尝试对该zip文件进行ant询问。一旦你确认它是有效的，那么你就知道你的蚂蚁任务是有效的。然后我将重点关注ear文件是如何生成的。
