IndexOutOfBoundsException解压缩耳朵文件时

Question

This is one of the target in my deployment script and it tries to unzip an .ear file. It fails with IndexOutOfBoundsException.

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

How do I figure out what is causing this exception? What list/array is this accessing that causes this exception?

Stacktrace:

Answer 1

It sounds like you have a corrupt ear file. I would suggest creating another zip file and try your ant ask on that zip file. Once you confirm that it works then you know your ant task is working. Then I would focus on looking at how the ear file is being generated.
