maven如何重新部署java web app cargo

Question

亲爱的朋友们，我正在用cargo-maven2-plugin运行我的java web应用程序。当我跑的时候

mvn cargo:run

一切正常，但我修改了我的源代码并运行

mvn cargo:redeploy

我得到以下错误：

        [INFO] [talledLocalContainer] 18:17:04,411 [ContainerBackgroundProcessor[StandardEngine[Catalina]]] ERROR org.apache.catalina.core.ApplicationContext (ApplicationContext.java:675) - Servlet InitServlet threw unload() exception

它仍然以这种方式存在。 我怎样才能解决这个问题
