I installed a sonar server on my own pc (Windows XP), and I deployed sonar on Tomcat with a MySQL database. I successfully analysed an old project. But with my current project, I get this exception when trying to execute mvn sonar:sonar:

我不理解问题产生在何处。 谁有答案? 这能否来自我的POM配置?

PS: 指挥线路mvn Cleanstal>和mvn Site工作正确......
