The Nexus Professional 1.4 release offers a wide array of features
- Proxy Repository Browsing - With Nexus 1.4, the local cache and logical index views have been separated into separate tabs. We found that the previous single tab with a combo box to select the source was confusing.
- Publishing Web Sites to Nexus Professional - Nexus Professional 1.4 provides you with a WebDAV endpoint for publishing a web site. You can configure a Site repository that can be used as a publishing destination for project documentation. This means you don't have to worry about providing some alternate solution to host your reports. The full support of Nexus security applies to this new type of repository, so you can control access at a very fine grained level.
- Repository Configuration Changes
- Fine-grained control of Redeployment for Hosted Repositories: Nexus 1.4 provides administrators a simplied way to control how a hosted repository deals with the redeployment of artifacts. You can configure a repository to allow for the redeployment of previously deployed artifacts, allow for one-time deployment, or to provide a read-only interface for clients.
- Improvements to the Staging Plugin - The staging plugin had numerous improvements in the 1.4 release to increase usability and provide new functions for staging artifact bundle and verifying that staging repositories follow user configurable rule sets.
- Support for Staging Rulesets: Nexus Professional 1.4 provides administrators with the ability to define a set of rules to apply to staging repositories before they can be promoted. The 1.4 release can validate that staging repositories contain valid POMs, valid PGP signatures, javadocs, and sources for all artifacts. The rules are pluggable and we expect to add more rules in the near future to support the Apache repository and our OSS hosting repository
- Support for Uploading Artifact Bundles: The staging plugin now accepts artifact bundle uploads. Artifact bundles are archives which contain one or more associated artifacts, they are used to publish artifacts to the Central Maven repository, and you can use Artifact bundles to validate artifacts uploaded to Nexus.
- General Usability Improvements in the Staging Plugin: This release of the Staging plugin focused on usability, the Staging plugin is full of improvements that make the user interface more intuitive and easier to use.
- User Account Plugin - The User Account Plugin in Nexus Professional gives unauthenticated Nexus users the ability to sign-up for a Nexus account. When this feature is enabled, a new user would click a sign-up link, fill out a simple profile form, read a captcha, and then activate a new account via an email confirmation message. Nexus Administrators can configure the default roles and permissions that are granted to newly signed up users.
- Repository Summary Panel - The repository summary panel provides statistics and configuration information for a specific repository. Users can consult the repository summary panel to gather the necessary distribution management settings for Maven configuration.
- Security Improvements - Many improvements to the user security model. In general, it is now easier to configure custom role mappings for externally managed users, and Sonatype has paid close attention to the user interface for managing users and roles. It is easier than ever to configure and secure a Nexus repository.
- New User Role Tree: Click on a user and then click on the user role tree to see how each role contributes to the permissions for a particular user.
- New User Privilege Trace feature: this features allows Nexus administrators to pinpoint which roles contribute which permissions to a particular user. While the user role tree provides an intuitive interface that lists role in a hierarchy, the privilege trace panel under user administration provides an alternate view. Click on a particular permission to find the roles contribute that permission to a user.
- New Role Tree: Since a Nexus role can consist of both roles and privileges, we've provided an intuitive tree browser that allows an administrator to browse the hierarchy of roles and privileges associated with a Nexus Role.
- Fine-grained control of View Repository Privilege: Nexus added the ability to configure a role to prevent users from browsing particular repositories. This is used to provide a cleaner view to users, for example to show them only groups they use via Maven and not confuse them with all the repositories aggregated by that group.
- Integration with Atlassian Crowd - Atlassian Crowd is a capable user and directory management system that can consolidate authorization and authentication to a central server. Nexus Professional's Atlassian Crowd plugin provides seamless integration between Nexus and Atlassian's Crowd server.
- Automated Nexus Error Reporting - Nexus 1.4 ships with an automated error repository system which can be configured to report Nexus exceptions and errors to the Nexus Issue Tracker. If configured, the system will send data to Sonatype's Jira instance. The information contained includes the configuration (all passwords are obfuscated) as well as a file list of the repositories and exception traces. All of this data is encrypted using public-key cryptography so only Sonatype can view the contents. We expect that this information will allow us to further refine the stability of Nexus.
