Type in an artifact or group identifier, a class name, or a checksum.
Press Enter.
Once you have located the artifact you were looking for, click on the artifact and copy the dependency XML from Nexus to your POM. It couldn’t get any easier or intuitive. Make sure to bookmark http://repository.sonatype.org.
If you are looking for the easiest way to search for artifacts in the Central Maven Repository, go to http://repository.sonatype.org. Sonatype maintains a publi instance of Nexus that can be used to search for artifacts by GAV (groupId, artifactId, version) coordinates, Class Name, or Checksum. Here’s a brief demonstration of the search capabilities on http://repository.sonatype.org.

A common question from Apache Maven users is “How do I search the central repository?” or “How do I find out what groupId or artifactId I should use for a specific dependency?” Use Sonatype’s Nexus installation at http://repository.sonatype.org to search multiple repositories at once. Sonatype has an instance of Nexus serving as a mirror of a number of repositories including Central. If you are looking for the right XML to put in your project’s POM for a dependency like Log4J or ActiveMQ, just load repository.sonatype.org in your browser..
Nexus gives you control over the repositories your builds interact with. It can also provide you with an easier way to publish, distribute, and manage the software applications you create. You can get started by downloading Nexus Professional and reading the free Nexus book.
