Maven project dependency "could not find artifact"

I have 2 maven projects. Project A and Project B. Project B is dependent on Project A but not the other way around.

In my project B pom I have this:

    <dependency>
        <groupId>com</groupId>
        <artifactId>ProjectA</artifactId>
        <type>pom</type>
        <version>1.0-SNAPSHOT</version>
    </dependency>

When i try to package the project it fails with this error:

 [ERROR] Failed to execute goal on project ProjectB: Could not resolve    dependencies for project com:ProjectB:war:1.0-SNAPSHOT: Could not find  artifact com:ProjectA:pom:1.0-SNAPSHOT -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal on project ProjectB: Could not resolve dependencies for project com:ProjectB:war:1.0-SNAPSHOT: Could not find artifact com:ProjectA:pom:1.0-SNAPSHOT

So it can't find my ProjectA pom. Do I need to put it in my project? Where should it be located in my file structure.

For what it's worth, I am using intelliJ IDE.

Thanks in advance.

EDIT: When i run install on projectA I get this error:

The packaging for this project did not assign a file to the build artifact

EDIT2 - Adding ProjectA pom:
