How do I prevent Maven from downloading artifacts every time?

I’m using Maven 3.1.1. In one of my projects, I reference another one of my projects …

    <dependencies>
            <dependency>
                    <groupId>org.mainco.subco</groupId>
                    <artifactId>myprojectA</artifactId>
                    <version>${project.version}</version>
            </dependency>

The above is dependent on a couple other of my projects. However, when I run “mvn clean install,” Maven attempts to download these artifacts instead of just using what’s in my local repository. How do I get Maven to only download things if they do not exist in my local repository? Here’s the output of what I’m seeing …

davea$ mvn clean install

If you use offline flag it will use your libraries from local repo.

mvn clean install -o
