Gradle + jetty + Spring MVC failed to start the project - Codes Helper

I am currently looking at the fourth edition of "Spring in action" and want to follow the actual project started in Chapter 5 of the book, but I have encountered some problems when starting the project using gradle and jetty.

Code is basically copied from the book, paste several key configuration files:

this is the configuration file for sevelet

package spittr.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

import spittr.web.WebConfig;

public class SpitterWebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[]{RootConfig.class};
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[]{WebConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }

}

this is the root configuration file:

package spittr.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ComponentScan.Filter;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration
@ComponentScan(
        basePackages = {"spittr"},
        excludeFilters = {
                @Filter(type = FilterType.ANNOTATION, value = EnableWebMvc.class)
        })
public class RootConfig {
}

Note that all java-based configurations are used, and there are no xml files.

the jsp code is as follows:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<html>
<head>
    <title>Spitter</title>
    <link rel="stylesheet"
          type="text/css"
          href="<c:url value="/resources/style.css" />">
</head>
<body>
<h1>Welcome to Spitter</h1>

<a href="<c:url value="/spittles" />">Spittles</a> |
<a href="<c:url value="/spitter/register" />">Register</a>
</body>
</html>

build.gradle is as follows:

apply plugin: "war"
apply plugin: "idea"
apply plugin: "java"
apply from: "gretty.plugin"

dependencies {
    compile "org.springframework:spring-webmvc:4.0.7.RELEASE"
    compile "javax.servlet:jstl:1.2"
//    providedCompile "javax.servlet.jsp:jsp-api:2.1"
//    providedCompile "javax.el:javax.el-api:2.2.4"
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    maven{ url "http://maven.aliyun.com/nexus/content/groups/public/"}
    maven { url "http://maven.springframework.org/release" }
    maven { url "http://maven.springframework.org/milestone" }
    maven { url "http://maven.springframework.org/snapshot" }
    maven { url "http://download.java.net/maven/2" }
    mavenCentral()

}

war {
    baseName = "spittr"
    version = "0.1.0"
}

when I run the gradle appRun command to start the server, I get the following information:

One of the strange things about

is that the progress indicator card is not moving at 87%. Visit http://localhost:8080/Spittr Times error message is as follows:

but obviously gradle installed jstl 1.2 for me during the build project. Why?
