Добавление Spring Security taglib создает ошибки, когда tomcat инициирует бобы

Я работаю над школьным проектом с использованием Spring MVC (Spring 3.0.0).

Теперь все работает так, как должно, пока я не добавлю Spring Security taglib в pom.xml с использованием

<dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>org.springframework.security.taglibs</artifactId>
        <version>${spring.version}</version>
</dependency>

(возможно, стоит отметить, что пока я не добавлю следующее Maven repo, он даже не сможет найти taglib).

<repository>
        <id>com.springsource.repository.bundles.external</id>
        <name>EBR External Release Repository</name>
        <url>http://repository.springsource.com/maven/bundles/external</url>
</repository>

Ошибка, которую я получаю, выглядит следующим образом:

У кого-нибудь есть любая идея, что я делаю неправильно? Я рву на себе волосы из-за этого.
