Eclipse JarRetriever

Eclipse JarRetriever is a plug-in for Eclipse that allows developers to easily search for and download jar files from Maven repositories.

The plug-in adds an "Add a Jar from the Internet" option to the right-click menu for each Java project. Selecting this runs a wizard which lets you search for a library, and shows all known versions. After you select the required version, it is downloaded to a location of your choosing and added to the project classpath.
