如何将包从一个项目导入到另一个项目

Question

I have two projects (let say project A and project B) the two works with Spring( The same version)the only difference is that the first one has an Eclipse IDE and the second one STS and I want to use and work with the project A in the project B.

I've tried to manually copy/past a number of classes but the classes are so much dependent between them it makes it impossible.

I expect to show me how to import/export project A and use it in project B

Answer 1

Basically project A should be in your build path. Any of the two ways works

• Export your project A as jar and add the jar to your Project B's build path.
• Projects BuildPath > Projects > Add your project A.

Answer 2

Basically the one above me is really close , but If you will export project A to jar it might be not work if you want use it on server (Tomcat for example). So you can make it "Runnable jar" from the first place and then as he said : project B (right click) >>>> build path >>>> configuration path >>> libraries >>> add external jar >> and browser when you saved the jar. now you can make instance of projects A classes and the functions already inheritance . glad it helps you :)
