java - Tomcat ClassPath 不适用于 Javac 编译

问题描述

我正在尝试在我的 tomcat 类路径上编译一个 servlet，即使我相信我有正确的命令，它也不会工作。我想使用 json utils 进行解析和明显的 servlets api。但是，我无法找到该包裹。我重新安装了java，即java 11，我还重新安装了Tomcat，即Tomcat 10。这是在Windows机器上。

这就是我在控制台中所做的以及输出的内容。

 D:\Tomcat\apache-tomcat-10.0.2\webapps\helloservlet\WEB-INF>javac -cp 
   ".;D:/Tomcat/apache-tomcat-10.0.2/lib/servlet-api.jar;D:/Tomcat/apache-tomcat- 
  10.0.2/lib/tomcat-util.jar;.;" -d classes src\mypkg\HelloServlet.java -source 
   1.8 -target 1.8
