I started my current gig at the end of last year. I've been enjoying the work and especially the project infrastructure we've been using. We're using the usual suspects: JIRA, Confluence, Hudson and Subversion. We're also using a couple new ones, namely sventon and Nexus. For building, we're using Maven and Ivy (as a Grails plugin).
I'm writing this post to talk about Nexus and how much I've enjoyed using it. I like Nexus for two reasons: it's aesthetically pleasing and it's well-documented. Another reason I really dig it is because I haven't had to touch it since I first configured it. Software that just keeps on humming is always fun to work with.
In addition to on-the-job, I've started to use Nexus more and more in my open source life. With the help of Jason van Zyl, I recently moved AppFuse's repository to Sonatype's oss.sonatype.org. I also noticed there's a Nexus instance for Apache projects. If that's not enough, you can get Nexus Pro free if you're an open source project.
Personally, the open source version of Nexus seems good enough for me. While the Staging Suite looks nice, I think it's possible to do a lot of similar things with good communication. After all, it's not going to free you from having to wrestle with the maven-release-plugin.
Next week, I'm helping to polish and document our entire release process (from dev → qa → production). If you have any advice on how to best perform releases with Maven, Grails and/or Nexus, I'd love to hear about it. My goal is extreme efficiency so releases can be done very quickly and with minimal effort.
