As the title says, I'm just trying to run the javafx application. However I have no idea why I'm getting this error, and I don't know why the error is referencing the sisu.inject.bean and aopalliance modules. I don't know wether the module-info.java or the pom.xml is causing the error. Thanks in advance for any anwser.
module-info.java:
module ui {
requires javafx.fxml;
requires transitive javafx.graphics;
requires javafx.controls;
requires org.testfx.junit5;
requires junit;
requires core;
exports ui.java;
exports test.ui to junit;
}
pom.xml:

Error:
Error occurred during initialization of boot layer
java.lang.module.ResolutionException: Modules sisu.inject.bean and aopalliance export package org.aopalliance.aop to module org.testfx
Process finished with exit code 1
TL;DR — The two modules have a split package in common. And JPMS forbids split packages.
The long-winded version
The first sentence of this 2010 blog gives a summary of what a split package is…1
Keep in mind that was written in 2010 though; before JPMS. So the blog's claim of „without any problem at both compile and runtime“ in the second sentence is out-of-date; for the modulepath in any case.
For a way more detailed, more up-to-date explanation, watch this Project Jigsaw: Under the Hood video from JavaOne 2016.2
Because your project has a module descriptor (module-info.java) Maven has put those dependencies — which I can see you declared in your pom — on the modulepath.
Because JPMS abhors split packages…3
The solution
1 That blog talks about OSGi. But the core split package definition applies to JPMS too.
