使用 Eclipse IDE 在 java 中设置类路径

Question

I have an Eclipse project with an external folder containing a lot of JAR files (legacy libraries) . instead of adding all the jars in Eclipse ("add external Jar"), I would prefer to add a ref to this external folder. In the "configure build bath", I'm adding a "External Class Folder". If I'm doing that instead of adding the Jar, my program is not compiling anymore. Am I missing something on the way I should use this option ?

Thanks

Answer 1

Try this:

Project -> Properties -> Java Build Path -> Add Class Folder.

If it doesnt work, please be specific in what way your compilation fails, specifically post the error messages Eclipse returns, and i will know what to do about it.

Answer 2

You can create new User library,

On

"Configure Build Paths" page -> Add Library -> User Library (on list) -> User Libraries Button (rigth side of page)

and create your library and (add Jars buttons) include your specific Jars.

I hope this can help you.

刚刚遇到了同样的问题，对于那些有相同问题的人来说，可能是您将库放在模块路径而不是类路径上，同时将其添加到您的项目中
