Question

For a newly created project B, I need to build the path the exactly same way as an existing project A. After opening the “java build path” window by clicking “build path–> configure path”, I found that There are a lot of libraries involved in Project A. How to handle this kind of scenario? Add those jar files one-by-one?

Answer 1

If you can locate all those jars on your file system/network, the best thing for you to do is to create an eclipse User Library.

Creating a Library

Window >> Preferences >> Java >> Build Path >> User Libraries

• Select New
• Give your library a name
• Ok
• Select Add Jars
• Add all the jars you need for your library

With this library created, you can share the same jars between projects easily by importing the library as opposed to each individual jar file.

Importing a Library

For each project that needs a particular library all you have to do is import the library.

• Open the project’s properties
• Select Java Build Path
• Select Libraries tab
• Select Add library
• Select user Library
• Select your Library you created
• Finish

Note

User Libraries do not belong to projects, they belong to the User but can be referenced by multiple projects.

Using libraries allows you to update your jars only once for all projects that share the same jars.

I hope that helps 😀
