Spring RestTemplate added, Exception on launch to Tomcat7

Question

I've added code to implement a RestTemplate Client to my Spring MVC project (Eclipse, Maven, Spring 3.1.0.RELEASE). Everything builds and when I launch to Tomcat7, I get the output below. Is it possibly a Spring artifact I'm missing in the pom.xml? I've got

• spring-webmvc (excluding commons-logging)
• spring-oxm
• spring-security-web
• spring-security-config
• spring-tx
• spring-aop
• spring-orm
• spring-test
• apache httpclient (excluding commons-logging).

org.springframework.beans.factory.BeanCreationException: Error creating bean . . nested exception is java.lang.NoClassDefFoundError: org/apache/http/auth/Credentials

You need apache http components:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
     <version>4.1.1</version>
</dependency>
<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpcore</artifactId>
