Today I tried to use leiningen on a development machine where I had set up a network-local nexus repository for my maven distribution management. And it took me some minutes to get leiningen to work, because it always failed with a message like this:
----------
1 required artifact is missing.
for artifact:
org.apache.maven:super-pom:jar:2.0
from the specified remote repositories:
clojure (http://mylocalrepository/nexus/content/groups/public),
clojars (http://mylocalrepository/nexus/content/groups/public),
clojure-snapshots (http://mylocalrepository/nexus/content/groups/public),
central (http://mylocalrepository/nexus/content/groups/public)
at org.apache.maven.artifact.resolver.DefaultArtifactResolver.resolveTra
nsitively(DefaultArtifactResolver.java:324)
at org.apache.maven.artifact.ant.DependenciesTask.doExecute(Dependencies
Task.java:170)
... 34 more
I noticed that there was the URL to http://mylocalrepository in the error messages and that I probably hadn't all the clojure stuff configured there. In fact, I didn't think about that at all. I don't want the clojure dependencies to live in that repository, so I have to exclude it from my maven mirror settings in USERDIR/.m2/settings.xml:
<mirrors>
<mirror>
<id>nexus</id>
<!-- use this mirror for everything excluding clojars and clojure: -->
<mirrorOf>*,!clojars,!clojure</mirrorOf>
<!-- use this mirror for all external repositories:
<mirrorOf>*</mirrorOf>
-->
<url>http://mylocalrepository/nexus/content/groups/public</url>
</mirror>
</mirrors>
After that leiningen downloaded all the dependencies and was generally more helpful. ;-)
