Tomcat localhost 的 v9.0 服务器遇到问题 -- 原因：java.io.FileNotFoundException

Question

我正在尝试运行 Tomcat Eclipse 中带有 2 个 jar 文件的 v9.0 服务器：

taglibs-standard-impl-1.2.5.jar taglibs-standard-spec-1.2.5.jar

但我一直运行ning 这条错误消息：“本地主机上的服务器 Tomcat v9.0 服务器无法启动。”错误日志表明它是由 Caused by: java.io.FileNotFoundException:C:\Users\abdc\eclipse-workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\PM4\WEB-INF\lib\taglibs-standard-impl-1.2.5.jar (The system cannot find the path specified)

引起的

我仔细检查了我的 jar 文件路径，它们与项目的其余部分位于正确的位置：

C:\Users\abdc\Desktop\WebContent\WEB-INF\lib\taglibs-standard-impl-1.2.5.jar C:\Users\abdc\Desktop\WebContent\WEB-INF\lib\taglibs-standard-spec-1.2.5.jar

如有任何见解，我们将不胜感激。这是我的错误日志：

路径错误，您必须将您的 jar 文件粘贴到此路径中：

C:\Users\abdc\eclipse-workspace.metadata.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\PM4\WEB-INF\lib\
