Nexus manages Maven software artifacts required for development, deployment and provisioning. If you develop software using Apache Maven, Nexus can help you share those artifacts with other developers and end-users.
Accounts are the same as OW2 Forge accounts.
This detailed user guide explains how to use the OW2 Nexus installation.
The release managers should read the migration guide.
Pushing releases/snapshots is only authorized after the project has been declared to the Nexus instance (read here).
