出现这个错误的原因是在某一个JSP里面没有到java.util.*的包

Unable to compile class for JSP:

Only a type can be imported. java.util resolves to a package

<%@ page language="java" contentType="text/html; charset=UTF-8"
         pageEncoding="UTF-8" import="java.util.*"
         isELIgnored="false"%>
<form action="addProduct" >
    产品名称：<input type="text" name="name" value="">
    产品价格：<input type="text" name="price" value="">
    <input  type="submit" value="增加商品">
</form>

自己检查了下，有个jsp页面导包写错了，起初是

import="java.util

改为

import="java.util.*
