How do I force Maven to wait for all modules in parallel to finish running?

Question

I’m using Maven 3.2.3. I am running a multi-module project, which contains

    <modules>
            <module>module-A</module>
            <module>module-B</module>
            …
            <module>module-X</module>
    </modules>

If I run “mvn clean install -T 2”, the modules “module-A” and “module-B” will run in parallel because there is no dependency between either. However, I’m noticing that if module-B fails while module-A is still running, execution stops altogether and the result of “module-A” is reported as “SKIPPED”. How do I force Maven execution to not halt until all the currently running modules are finished (in my case, it's a big problem that module-A aborts halfway through).

Thanks, - Dave
