eclipse - 使用Maven和Eclipse运行Tomcat-未知生命周期阶段

Question

我正在使用Eclipse Helios，Tomcat Server7。已经使用Maven构建了我的项目。当我尝试构建项目时，在Eclipse中出现以下错误。

请让我知道我的代码出了什么问题，并请指出正确的方向。我需要尽快弄清楚。

这是我的pom.xml。我正在尝试从Eclipse运行as-> mvn build来运行我的应用程序。

听起来您在尝试从Eclipse进行构建时意外地设置了错误的目标。像这样编辑您的Maven“运行方式..”设置:

注意clean install，它将运行Maven命令来清理您的构建并进行完整的构建并安装到本地存储库中。
