Configuration problem: spring-security-web classes are not available.

[pc175]

I have encountered 2 errors that seems doesn't make any sense:

Configuration problem: spring-security-web classes are not available. You need these to use <filter-chain-map>
Offending resource: file [/home/pc0/Documents/workspace/spring-samples/Spring3MVC/src/main/webapp/WEB-INF/spring-security.xml]

spring-security-web classes are not available. You need these to use <filter-chain-map>

The weird thing is that I already have spring-security-web class in my dependencies:

<!-- Spring Security -->
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
<version>3.0.5.RELEASE</version>
</dependency>

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

I have tried mvn clean but nothing changed. Anybody know how to fix it?

What is the value of spring.version? Perhaps you are not using the same version of Spring Security throughout? Can you provide a complete error including stacktrace? When and where are you seeing the error (i.e. in standard error/out when starting the application, in errors view of STS, etc)?
