如何使用其他项目的类？ [英] How to use classes from another project?

问题描述

我在Eclipse中有两个Java项目。现在我想在项目B中使用项目A中的类。我将项目A添加到项目B的构建路径中。但是项目B中没有类。

I have got two Java projects inside Eclipse. Now I want to use classes from project A in project B. I added project A to the build path of project B. But the classes are not available in project B.

这个问题可能是什么原因？
我做错了吗？
我应该怎么做？

What could be the reason for that problem? Did I do something wrong? What and how should I do?

提前致谢。

更新：问题是要导入的类是在默认包中。

Update: The problem was that the classes to be imported were in the default package.

推荐答案

验证是否在构建属性中在订购和导出选项卡下的项目A中，您已选中源文件夹。

Verify if in the build properties of Project A under the "Order and Export" tab you have the source folder checked.
