Problem with spring-security-web-4.2.0.RELEASE

[Alejandro Barrero]

I am working on my first web application with Spring Security on the STS IDE. I added to pom.xml

            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-web</artifactId>
            <version>4.2.0.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-config</artifactId>
            <version>4.2.0.RELEASE</version>
        </dependency>

I am getting an error message in the Markers view "'C:/Users/ABarrero/.m2/repository/org/springframework/security/spring-security-web/4.2.0.RELEASE/spring-security-web-4.2.0.RELEASE.jar' in project 'SpringSecurity' cannot be read or is not a valid ZIP file". I still get an error if I add the jar file directly to the build path. I have not been able to find this jar file in the Internet.
