Maven cannot compile Spring Security demo project

I resolved this by removing this line from pom.xml on the spring-security-config artifact:

   <scope>runtime</scope>

You need to add spring security library manually.

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>3.2.4.RELEASE</version>
</dependency>
