This happens with all versions of jenkins and with the newest version of the plugin and also with the current code in the master branch.
Just create a new job with type "maven 2/3" and add it to a phase. Configuring this setup is not an issue, but when you run it, you'll see that the multijob plugin will not be able to determine the status of the job. Instead, it will just start the next job and not wait until the maven job is finished. The status "ball" indicating the jobs status on the multijob status page will stay gray.
In fact the same thing happens when you add a matrix build job to a phase.
The fix is very easy, please see the PullRequest I have placed.
