JPro Maven build failing with UncheckedExecutionException

Question

I am trying to run a simple JavaFX JPro demo project using Maven.

This is my file structure:

C:.
├───.idea
├───logs
├───src
│   └───main
│       └───java
│           └───com
│               └───example
└───target
    ├───classes
    │   └───com
    │       └───example
    ├───generated-sources
    │   └───annotations
    ├───jpro
    │   └───fonts
    └───maven-status
        └───maven-compiler-plugin
            └───compile
                ├───default-cli
                └───default-compile

My pom file contains this code, based on the sample located here:

The problem is, when I run the code using mvn jpro:run, I get the following length stacktrace:

What causes this error? I suspect it has something to do with JavaFX, but I don't really know where to begin. How should I configure my project to get it to run?

Do you have a `module-info.java` file? Does this help? https://stackoverflow.com/questions/53477690/properly-implementing-java-modules-in-a-maven-build-with-inter-module-test-depen — Abra, Apr 14 '21 at 01:44

This happens because the version of JPro you are using doesn't support Java16.

It works with the newly released version 2021.1.1. (Which wasn't available when the question was asked)
