我在启动 Tomcat 服务器时遇到问题，它曾经可以工作，但我做错了什么，现在它向我抛出此异常:

I'm having trouble starting my Tomcat server, it used to work, but I did something wrong and now it throws me this exception:

Caused by: java.lang.IllegalArgumentException: The main resource set specified [E:workspace.metadata.pluginsorg.eclipse.wst.server.core	mp1wtpwebappsworkspacej2eeapplication	argetj2eeapplication-0.0.1-SNAPSHOT] is not valid

我在论坛上查看了不同的解决方案，但没有任何效果.最终选项将是卸载 tomcat 和全新安装，因为我读到这可能会奏效.提前感谢您的帮助.

I looked at different solutions over the forums, but nothing worked. Final option will be uninstalling tomcat and fresh installation, cause I read that might work. Thanks for the help in advance.

推荐答案

似乎您的 Tomcat 嵌入式服务器中引用了一个过时的 Web 应用程序(您正在 Eclipse 中使用 Tomcat As 对吗?).

Seems like you have an outdated web application referenced in your Tomcat embeded server (You are using Tomcat As within Eclipse right?).

首先检查您服务器中部署的应用程序，并检查工件名称​​j2eeapplication-0.0.1-SNAPSHOT和版本.您可能需要删除它并清理您的工作目录，然后重新部署它，您应该是安全的.

First checkout the deployed application within you server, and check the artifact name j2eeapplication-0.0.1-SNAPSHOT and version. You may need to remove it and clean your working directory the redeploy it and you should be safe.
