信息: 至少有一个JAR被扫描用于TLD但尚未包含TLD。 为此记录器启用调试日志记录以获取已扫描但未在其中找到TLD的完整JAR列表。 在扫描期间跳过不需要的JAR可以缩短启动时间和JSP编译时间。

Caused by: java.lang.IllegalArgumentException: 指定的主资源集 [D:\eclipse4.14Code\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\Web3] 无效我们可以清晰的读到加载Web3这个项目无效
于是我们找到Server这个工程 这个Server工程是我们在启动Tomcat时自动生成的一个工程该工程里面包含Tomcat的重要信息切记不可以删除掉。这里可以看到我运行了4个Tomcat所以会出现四个Tomcat的文件夹每一个Tomcat文件夹包含当前Tomcat配置的重要信息我们打开红色箭头指向的文件 红色框框处的这行代码是以前Tomcat运行Web3这个项目时生成的一条记录 现在Web3这个项目既然已经无法运行了我们将其注释掉重启即可解决问题
最终运营结果
看到箭头处表明我们的Tomcat工程启动成功
