Issues with Shiro Security. Why doesn't it find the EnvironmentLoaderListener class?

Question

Java

There is a simple REST service based on Jersey. It is necessary to "welcome" Shiro.
There are problems during deployment. But everything is in order.
web.xml

<servlet>
    <servlet-name>Application</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>alexiuscrow.ws</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>Application</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

<filter>
    <filter-name>ShiroFilter</filter-name>
    <filter-class>org.apache.shiro.web.servlet.ShiroFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>ShiroFilter</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>INCLUDE</dispatcher>
    <dispatcher>ERROR</dispatcher>
</filter-mapping>

Gradle dependencies:

dependencies {
    compile 'org.glassfish.jersey.core:jersey-server:2.19'
    compile 'org.glassfish.jersey.containers:jersey-container-servlet:2.19'
    compile 'org.apache.shiro:shiro-core:1.2.3'
    compile 'org.apache.shiro:shiro-web:1.2.3'
}

During deployment, I get an exception:

18-Jul-2015 21:28:10.775 SEVERE [RMI TCP Connection(2)-127.0.0.1] org.apache.catalina.core.StandardContext.listenerStart Error configuring application listener of class org.apache.shiro.web.env. EnvironmentLoaderListener
java.lang.ClassNotFoundException: org.apache.shiro.web.env.EnvironmentLoaderListener
//...

What is the problem?
