我已经通过 Eclipse 方式创建了 tomcat 项目。我在原型选择阶段选择了tomcat原型。它为一个项目创建了 6 个目录，包括“-api”、“-api-impl”等。
现在我该如何运行？
在命令行我可以发出
mvn tomcat6:run
或者
mvn tomcat7:run
它会运行。
如何在eclipse中做同样的事情？
更新
可能这个命令相当于 ->Debug As... 并在“goals”中输入“tomcat6:run”。但在这种情况下，我会收到类似的错误

如果我设置调试输出，我会得到“连接被拒绝”异常：

解决方案
防病毒防火墙阻止 eclipse 访问网络。因此，从 Eclipse 中运行目标失败了。
