Nexus Repository Manager 3.24.0


These notes are a compilation of new features and significant bug fixes for Nexus Repository Manager 3.24.0.

See the complete release notes for all resolved issues.

New and Noteworthy

Export for Raw and Maven formats (Pro Only)


Export enables customers to export Raw and Maven contents from any repository to a target folder. The exports can then be imported into another repository in the same instance or a totally different instance. This is a great way to migrate content between two or more Nexus Repository Manager Pro 3 installations. Future releases will incude additional support for NuGet, NPM, RubyGems, Yum, Docker, and PyPI.

To use Export, configure the task from Settings → Tasks → Create Task → Repository - Export assets as shown here:

NuGet V3 Hosted Support


NuGet V3 Hosted support gives Nexus Repository users access to the up-to-date V3 API. This is the second part of a wider initiative to bring full V3 support (Proxy, Hosted, and Group). Group repository support will be the final stage in an upcoming release.


Several new and improved REST endpoints in this release. See below tickets for specifics including upgraded Blobstore, Atlassian Crowd, and Nexus IQ endpoints. New REST endpoints have also been released including CocoaPods, Maven Group, Raw, and RubyGems repositories.

REST v1 endpoints (beta endpoints still active and fully functional)

General Improvements

  • [NEXUS-23897] Memory settings in docker image standardized to our recommended minimums
    (warning) This changes default memory allocations from 1200m to 2703m as well as a larger heap. If your instance cannot handle these settings you may need to make manual adjustments but be aware your instance is likely under resourced in this case.
  • [NEXUS-23870] "Node already has an asset" for browse tree rebuild no longer fails Transactions status check

Bug Fixes


  • [NEXUS-23903] Long running database queries for Docker repositories can lead to thread and db connection pool exhaustion performance

Maven, Scheduled Tasks

  • [NEXUS-23800] Race condition in lazy maven metadata rebuild causes build failures, slow builds


  • [NEXUS-23872] Unable to set repository HTTP client auth via REST


  • [NEXUS-19529] Viewing the UI repositories list will trigger s3 blobstore metrics retrieval even if that blobstore is not used

Nexus Repository Manager 3.23.0


We are pleased to present Nexus Repository Manager 3.23.0.

Import for Raw and Maven formats (Pro Only)


In Nexus Repository Manager 3.23.0, we focus on importing content from an external source and for a subset of formats. This can help customers migrate content from Nexus Repository Manager 2 to Nexus Repository Manager 3 at their own pace.

Import is implemented as a task. You can configure the Repository - Import external files task from Settings → Tasks → Create Task as show here:

Nexus Intelligence via npm audit


We are excited to announce enhanced Javascript support with Nexus Intelligence via npm audit for Nexus Repository Manager. Nexus Intelligence via npm audit will allow developers to check for policy violations in their Javascript projects, using the npm audit command built into the npm CLI, coupled with the precise data of Nexus Intelligence. Running the npm audit command lists all known vulnerable dependencies from your package.json file while gaining the benefits of the most precise intelligence regarding security vulnerabilities, license risk, and architectural quality of open source components.

This feature will be available to both Nexus Repository OSS and Pro users and will require a license of Nexus Firewall or Nexus Lifecycle (Nexus IQ version 89 and above). Nexus Repository Manager admins can enable Nexus Intelligence via npm audit across all development teams without having to modify any setup on the developers’ machines.
