Delivering on a Promise: Free Nexus Training

Our promise to the community was that when we reached 1,000 members we’d publish another series of free training videos. As of today, we have reached 1,061 members with the count growing daily. We are publishing the beginning of a new series on Nexus Pro and Smart Proxy as a thank you to the community for your continuing support. Current members have immediate access to the new series.

Rubyists Rejoice - Nexus Supports RubyGem Repositories

We have done it again! Our Nexus development team has been busy this fall. With Nexus 2.9 in September, we introduced NuGet support for Nexus Open Source. In October Nexus 2.10 introduced npm support for all Nexus editions. And now with Nexus 2.11, we are adding Ruby Gem Repository support!

We are happy to announce that Nexus 2.11 adds full support for Ruby Gem repositories to all Nexus editions including Nexus Open Source, Nexus Professional, and Nexus Professional CLM Edition.

Christian Meier, active JRuby committer and creator of the JRuby Maven plugin has maintained an open source project to support Gem repositories for Nexus with us for quite a while. However this integration was not part of a default Nexus install and users had to build and install the plugins themselves. To improve the experience for everyone, we have worked together to bring this capability into the main Nexus Open Source project and therefore into the default install of any Nexus edition. On the way the Nexus development team and Christian improved the codebase and solidified the features. Christian’s deep experience with Ruby and gems, helped ensure that we create the features needed to make Gem repository support in Nexus viable for real-world production use.

The new Gem repository support brings the tried and tested concepts used for Maven, NuGet and NPM repositories of combining proxy and hosted repositories in a group and exposing them to the client tools for Ruby, gem and Bundler users.


First create a proxy repository of the main RubyGems repository. This will allow you to take advantage of the proxy features of Nexus. Any gem downloaded by a users will be cached in Nexus and subsequent requests will no longer have to reach out to rubygems.org. This will reduce your bandwidth needs and make any gem install on subsequent systems more reliable and much faster, since the gem will be local on your network already. And you will have access to all the gems available at RubyGems.org and potentially any other gem repository you want to access without relying on the performance of that upstream repository for each request.


Then create a hosted repository for you own gems that you wish to distribute within your organization. This allows you to push a gem to Nexus and all other users can just install the gem on their system without any need for further custom tooling. A simple ‘gem install GEMNAME’ will do.

Optionally you can also create another hosted repository to host other gems, maybe from a proprietary vendor or partner organization, that doesn’t use Nexus yet.


Finally to make it super simple for your users, you create a Gem repository group. It merges the proxy and hosted repositories and exposes all the contents via one simple URL. This URL stays the same even if more gems are added to the repositories or if more proxy repositories are added to the group. Its truly a fire and forget configuration that just works.

And Enjoy!

Your users now have configure gem on their machine to use Nexus as a source. And if they want to push to Nexus they can use the nexus gem we provide.

All you have to do is get new Nexus 2.11 - Open Source or Professional, install it and get it configured and you are up and running. It will be quick and easy with the documentation and the benefits will be immediate. If you are using Ruby, If you are a Ruby developer, give it a try and let us know how you like it.

Integrating with SonarQube

Many development organizations we work with have turned to SonarQube as a dashboard to visualize and measure their code quality.

Insight For CI at the Jenkins User Conference

Before JavaOne 2012 a few of us joined the Jenkins community at the Jenkins User Conference 2012 in San Francisco as Gold Sponsors. We had a great time talking to KK, Andrew and others as well as showcasing Insight For CI for Jenkins at the booth. The presentation about "Improving Software Quality Using Component Lifecycle Management with Jenkins" was very well attended and there seemed to be a lot of interest. In case you missed it you are however in luck ...

The Time to Pay Attention to Application Security is Now

When we announced Insight for CI a few weeks ago, our message was simple "Get Proactive about Security with Insight". A few months ago, when we introduced the Repository Health Check in Nexus Professional, we had a similar message about licensing, "Lead or Be Led to OSS Compliance". For months we've been making the case that the time to worry about application security is now.

Get proactive about Security with Insight

There's a shift in the way organizations are thinking about security, and This article in Infoworld "IBM: Security execs move more toward active risk management" is exactly what we've been talking about. Here's the quote that stood out:
