This article has good tips how to increase the build time using maven:

I’ve addapted it for the IntelliJ idea IDE:
In short, for IntelliJ Idea change the following
in parameters add(inside the Run/Debug Configurations):
install -DskipTests=true -offline
it’s better to use install instead of the clean install because most of the time clean is not required, -DskipTests=true will skip the tests and -offline won’t download any snapshots that already exists.
in General, in Threads (-T option) add 1C, this means that each core will dedicate one thread for building
In Runner, in the VM options add:
-XX:+TieredCompilation -XX:TieredStopAtLevel=1
this is the Java VM options for speeding up the build
Alternatively, you can add the only project that you actually need
Ex: instead of install -DskipTests=true -offline use
install –pl YOUR_MODULE -am -DskipTests=true -offline
pl makes Maven build only specified modules and not the whole project.
am makes Maven figure out what modules out target depends on and build them too.
