Why can't Maven build resolve Spring @Bean @Configuration etc annotations?

Question

I'm trying to move my Spring MVC project to 3.2.4.

When I attempt to run up the application in IntelliJ, using Maven as I had done previously, I am getting errors about not being able to find a series of annotation classes from Spring...

@Bean
@Configuration
@ComponentScan
@PropertySource

are all failing with unable to resolve class error messages.

Other annotations are ok, which makes me think it is a dependency issue, as the Spring version is the main change in my project codebase.

Has Spring 3.2.4 changed where those annotations live in the packaging?

My current pom (some bits removed for brevity):

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"    
    <!-- SNIP project naming etc, nothing changed from before moving to 3.2.4 -->

    <spring.version>3.2.4.RELEASE</spring.version><!-- 3.2.4 -->
    <spring.security.version>3.2.0.RC1</spring.security.version>
</properties>

Solution

There is a duplicate dependency of org.springframework:spring-context in your POM that is probably causing classpath conflicts. The first one is a compile dependency using version 3.2.4.RELEASE, and the second one is a runtime dependency using version 3.0.0.RELEASE.

I suggest you remove the second since it's unnecessary and should be superseded by the first.
