How to deal with "omitted for conflict with.." message in pom.xml? - spring

Question

I have this situation:
I know that "Maven resolves version conflicts with a nearest-wins strategy". So here wins the aop 3.0.7 based on this rule. But i also define a dependencyManagement section in my pom and it seems like this:
<properties>
<org.springframework.version>3.2.4.RELEASE</org.springframework.version>
<org.springframework.security.version>3.1.4.RELEASE</org.springframework.security.version>
</properties>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>${org.springframework.version}</version>
</dependency>
</dependencies>
</dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${org.springframework.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
<version>${org.springframework.security.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
<version>${org.springframework.security.version}</version>
</dependency>
<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.7.1</version>
</dependency>
</dependencies>
</project>
And this is what it all looks like on the dependencies tab:
So i expect the spring-aop to use the 3.2.4.RELEASE version instead of 3.0.7 like the webmvc, as i define this in the dependeny management.. Why is there still being used the older version 3.0.7?

Answer 1

Your dependency management declaration has a typo (com.springframework instead of org.springframework).
This is the correct pom entry:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
Unfortunately, since the dependency is not being used, Maven (or Eclipse) will not flag as a missing artifact.
