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.

  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"

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.
