Digital Digressions by Stuart Sierra
From programming to everything else
In the early days of Clojure, I was skeptical of Clojure-specific build tools like Lancet, Leiningen, and Cake. Why would Clojure, a part of the Java ecosystem, need its own build tool when there were already so many Java-based tools? At the time, I thought Maven was the last word in build tooling. Early Leiningen…
I’ve been thinking about some of the tools that I use every day, and about the different design philosophies they reflect. Git First and foremost, Git. We use Git on every single project, internal and external. Git is a great example of the Unix design philosophy: many small programs — 153 of them by my…
This article attempts to unravel some of the mysteries of dependency management with Maven and Maven-based tools. Help, something’s missing! Say you have a project named “my-new-project” which declares a dependency on version 3 of the “awesome-sauce” library by the Example.com corporation. You add the dependency to your pom.xml, project.clj, or whatever configuration file your…
I hope I’ve demonstrated in the last few posts that Maven is pretty cool, not so scary. But the public Maven repositories sometimes leave a bit to be desired. They don’t have entries for every possible library, and occasionally they have incorrect dependencies or other metadata. Also, the process of adding new libraries to the…
I promised, in my previous post, that I would show you how to use the latest-and-greatest versions of Clojure and clojure-contrib in your Maven projects. Here’s that post. Formos Software maintains a Maven server with nightly builds of Clojure and contrib at http://tapestry.formos.com/maven-snapshot-repository/ Here’s a complete pom.xml file with dependencies on both Clojure and clojure-contrib:…
Update Sept. 4: How to get the latest builds of Clojure & Contrib Maven is a touchy subject. People tend to have strong opinions about it. But like it or not, it’s the de-facto standard for dependency management in the Java world. Clojure lives in the Java world, so that means we have to live…
