cannot access org.springframework.web.WebApplicationInitializer

Question

I am currently working through the example on scheduling tasks using Spring 4, Java 1.8, and Gradle (https://spring.io/guides/gs/scheduling-tasks/).

However, when running this example, I receive the following error:

Error:(11, 8) java: cannot access org.springframework.web.WebApplicationInitializer class file for org.springframework.web.WebApplicationInitializer not found

The source code to my Application.java is as follows:

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class);
    }
}

My gradle file:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.4.2.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'war'

jar {
    baseName = 'gs-scheduling-tasks'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter")
    testCompile("org.springframework.boot:spring-boot-starter-test")
    providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
}

Why is org.springframework.web.WebApplicationInitializer causing this error when it is not even mentioned in the guide?

Thanks.

Add this dependency to fix this problem. I perfectly worked for me.

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
