Changing pom.xml doesn't update libraries in Eclipse

Question

I have pom.xml like this:

...

<properties>
    <spring.version>3.0.5.RELEASE</spring.version>
</properties>

<dependencies>

    <!-- Spring 3 dependencies -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>${spring.version}</version>
    </dependency>

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

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

...

When I change spring.version into 3.2.2.RELEASE, nothing happens. I still have 3.0.5.RELEASE under Libraries build path.

I am using Eclipse Indigo SR2 with m2eclipse.

EDIT: Please mind, I am a newbie in maven world.

Solution 1

You need to update the project configuration manually. Project -> Maven -> Update Configuration

Update: Also set checkbox: Update Project Configuration from pom

Solution 2

Right-click on any project in the package explorer then select Maven. In maven select Update Project. or simply Alt + F5
