I managed to work out a solution for this.

1) I had to to to run configurations and add an argument to the VM. (Run - Run Configurations - JRE Tab - VM arguments). Enter the following in the text box

 -Dmaven.multiModuleProjectDirectory=%M2_HOME%

You need to use %M2_HOME% or something similar to represent the path to Maven, because when I added my path to that argument directly, it was unable to find it. I think it's because there is a length limit on the argument. My path was

C:\Program Files\Apache Software Foundation\apache-maven-3.3.1

and I got an error stating that it couldn't find the runtime at Program Files\Apache

2) Set up a system environment variable of called M2_HOME with C:\Program Files\Apache Software Foundation\apache-maven-3.3.1
