java.lang.IllegalArgumentException：指定的主资源集无效

Question

我在启动Tomcat服务器时遇到问题，它曾经工作过，但是我做了错误，现在它引发了这个异常：

Caused by: java.lang.IllegalArgumentException: The main resource set specified [E:\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\workspace\j2eeapplication\target\j2eeapplication-0.0.1-SNAPSHOT] is not valid 
    at org.apache.catalina.webresources.StandardRoot.startInternal(StandardRoot.java:643) 
    at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) 
    ... 9 more 

，这是我的web.xml：

我看着在论坛不同的解决方案，但毫无效果。最终选项将卸载tomcat和全新安装，因为我读过这可能工作。我在这里先向您的帮助表示感谢。

Answer 1

好像你在你的Tomcat服务器嵌入式引用过时的Web应用程序（你正在使用Tomcat作为的Eclipse右内？）。

首先检出您服务器内部署的应用程序，并检查工件名称j2eeapplication-0.0.1-SNAPSHOT和版本。你可能需要删除它并清理你的工作目录重新部署它，你应该是安全的。

Answer 2

我当我开始这是使用Tomcat 7

Answer 3

Maven的更新设计为Tomcat 8的伎俩，我的应用程序有此错误。

右键点击你的Maven项目：

• 的Maven>更新项目...
• 选择全部
• 检查
• 点击Ok

“快照/发布的强制更新”

现在，右键点击您的服务器：

• Clean ...
