Maven – Excluding Maven dependencies

I have a query about exclusion of maven dependencies . Consider the following

   <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-taglibs</artifactId>
        <version>${spring-security.version}</version>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.security</groupId>
                <artifactId>spring-security-web</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-web</artifactId>
        <version>3.1.0.RELEASE</version>
        <exclusions>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-web</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>3.1.0.RELEASE</version>
    </dependency>
    <dependency>

I am trying to achieve a transition from Spring 3.0.6 to 3.1.0 . Spring security 3.1.0 had a dependency on spring-security-web version 3.0.6 which in turn had a dependency on spring-web 3.0.6 . I need to bring it all to 3.1.0 . So I exclude spring-security-web from Spring security , have a separate dependency for spring-security-web 3.1.0 which in turn excludes the spring-web 3.0.6 version and I provide a separate spring-web 3.1.0 version . This work but I feel there would be a much easier approach . I tried putting an exclusion for spring web under Spring security but it didn't work . Please help .
