如何识别项目中包含的不必要的罐子？ [英] How can I identify unnecessary jars included in my project?

问题描述

我在Java项目中工作，其中使用了Apache的axis 2库。轴2库由大约20个jar文件组成，其中一些不用于项目。我想知道是否有一种方法可以识别哪些jar文件是未使用过的。

I'm working in a Java project where the axis 2 library from Apache is being used. The axis 2 library is composed of about 20 jar files and some of these are not used project. What I want to know if there is a method to identify which of those jar files are the unused ones.

我正在使用Eclipse IDE，我认为这是一种方式解决问题的方法是在时间上添加一个jar，直到我得到关于缺少的类的错误消息。但是，我不确定这是否会起作用，因为一些缺失的类错误仅在运行时出现。

I'm using the Eclipse IDE an I thought that one way to solve the problem is to add one jar at time until the I get no error messages about the missing classes. However, I'm not sure if this will work as some of the missing classes errors show up only at runtime.

有没有人知道更好的方法来解决这个问题？

Does anyone know a better way to solve this problem?
