Adding a JAR to an Eclipse Java library

Question

How do you add a JAR file to an already existing Java library in Eclipse? Note that this is not a user library.

That is, if you look at the Java Build Path for a Java project and click on the Libraries tab, you will see the list of libraries used by the project. If you expand a given library, you will see a list of JAR files included in that library. I want to add an additional JAR file to one of these libraries.

I am using Version 3.4.0 of Eclipse.

Answer 1

1. Select the library and click "Edit" (left side of the window)
2. Click "User Libraries"
3. Select the library again and click "Add JARs"

Answer 2

You might also consider using a build tool like Maven to manage your dependencies. It is very easy to setup and helps manage those dependencies automatically in eclipse. Definitely worth the effort if you have a large project with a lot of external dependencies.
