Nexus manages software components required for development, deployment, and provisioning. If you develop software, Nexus can help you share those components with other developers and end users. Nexus greatly simplifies the maintenance of your own internal repositories and access to external repositories. With Nexus you can completely control access to, and deployment of, every component in your organization from a single location.
Nexus is available in three editions:
- Nexus Open Source - Nexus OSS
- Nexus Professional - Nexus PRO
- Nexus Professional CLM Edition - Nexus PRO CLM
The basis of all Nexus versions is formed by Nexus Open Source. It is licensed under the Eclipse Public License version 1.0 and can be used to get started with component and repository management. It provides a plugin infrastructure for all its features and supports numerous repository formats out of the box.
Nexus Professional builds on top of the numerous features of Nexus Open Source and adds component information integration, improvements for the release process, improved LDAP integration and other features typically required by enterprises and advanced users.
Nexus Professional CLM Edition adds integration with Sonatype CLM to Nexus Professional. This makes your component management policies and rules configurable and actionable and provides further automation and integration with numerous tools to advanced users.
Upgrades from Nexus Open Source can be easily performed. This makes Nexus Open Source an easy, yet powerful solution to get started with component and repository management. Nexus Professional adds further features as well as full support by Sonatype.
