Hi all, I'm sorry to post here but I can't find a way to create an account on your issue tracking system. I get in the same trouble that is described here: https://jira.codehaus.org/browse/HAUS-2323
It seemed that the descriptor goal of "maven-plugin-plugin" version 3.3 is failing with java 8 and an interface with a default method, here are the information regarding my system: Apache Maven 3.0.4 (r1232337; 2012-01-17 09:44:56+0100) Maven home: D:\Users\clement.agarini\My Documents\apache-maven-3.0.4 Java version: 1.8.0_05, vendor: Oracle Corporation Java home: C:\Program Files\Java\jdk1.8.0_05\jre Default locale: en_US, platform encoding: UTF-8 OS name: "windows 7", version: "6.1", arch: "amd64", family: "dos" And here is the stack trace: [ERROR] Failed to execute
