Question

我是maven和servlets的新手，但我绝对是在我的智慧结束。它拒绝在每一个扭曲和转弯时工作，并且由于某种原因，它说“没有什么可以编译 - 所有课程都是最新的”，尽管我已经改变了所有要改变的东西。

这是我的servlet：

@WebServlet("/HelloWorld")
public class HelloWorldServlet extends HttpServlet {

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
    response.setContentType("text/html");
    response.setCharacterEncoding("UTF-8");

    String hold = request.getParameter("text");

    try(PrintWriter out = response.getWriter()) {
        out.println("<!DOCTYPE html>");
        out.println("<html>");
        out.println("<body>");
        out.println("<p>"+hold+"</p>");
        out.println("</body>");
        out.println("</html>");
    }
}

}

这是我的pom.xml：

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

我用来运行/调试的命令： mvn包装货物：部署
