Did you move the <reporting> section INSIDE the site plugin I had the same problem & fixed it by removing the reporting section And rewriting the maven-site-plugin section of the pom
See http://maven.apache.org/plugins/maven-site-plugin/maven-3.html Look at old configuration / new configuration -----Original Message----- From: nodje [mailto:[email protected]] Sent: Thursday, February 23, 2012 12:23 AM To: [email protected] Subject: Re: [maven-site-plugin] trouble migrating from 3.0-beta3 to 3.0, bug? Hum, I guess I can provide something. I can send you the smallest 'mvn site' failing project. Note that it does in a similar fashion on all failing projects. I've integrated the parent pom into the project pom for convenience, I hope it'll work without problem for you. I'll send it on you apache email. cheers Olivier Lamy [via Maven] wrote: > Hello, > Do you have a sample project to reproduce that ? > > 2012/2/22 nodje <[hidden email] > </user/SendEmail.jtp?type=node&node=5505481&i=0>>: > >> migration form 2.x to 3.0-betax wasn't much of a problem, but since > then, I >> had to release components and fix version. >> >> Now with maven-site-plugin:3.0, I have a recurring error and can't > find any >> information on it.
