Visit my.sonatype.com for documentation on Nexus Repository version 2.
If you see an errors or warnings in your Nexus Repository log about MKCOL, for example similar to:
2008-10-20 12:32:09.175 ERROR - org.mortbay.log: /content/repositories/releases/com/xxx/metier-utils-jar/01.24/ java.lang.IllegalArgumentException: No enum const class org.sonatype.nexus.proxy.access.Action.mkcol
This means you have a “dav:http://” url in your project POM distributionManagement section and are using WebDAV to deploy artifacts into Nexus. The MKCOL method is otherwise ignored by Nexus.
You only need an “http://” url to deploy to Nexus. HTTP PUTs will cause Nexus to create any required directories automatically.
