Unable to Access PredictiveErrorData and DensityData

Use case

I am trying to build a plugin, where i want to use prediction-intervals, but de.evoal.surrogate.adaption.interval.model.PredictiveErrorData seems to be not accessible, even though i added the dependency to pom.xml and require statement to module-info.java

Minimal Working Example

PredictionMeritCriterion.java module-info.java pom.xml

What is your question or problem

i am not sure, but i think the issue could lie with module-info.java inside de.evoal.surrogate.adaption? Maybe there should be some exports added, so PredictiveErrorData is accessible? The DensityData stuff is also not accessible, which i would need later as well
