Instead of running Quarkus, I’m running OptaPlanner through a Main class entry point in Kotlin.
This works great within Intellij where I have a simple Run Configuration set up for it.
object Main {
lateinit var solverFactory: SolverFactory<VehicleRoutingSolution>
lateinit var solver: Solver<VehicleRoutingSolution>
lateinit var scoreManager: ScoreManager<VehicleRoutingSolution, SimpleLongScore>
@JvmStatic
fun main(args: Array<String>) {
...
However, when I create an Intellij artifact for a jar and try to run it, I get this:
java -jar acme.jar

Shutting down
In solverConfig.xml I’m using <domainAccessType>REFLECTION</domainAccessType> because I cannot get Gizmo to work. I’m not sure if that’s related or not, but why is there a difference between an Intellij Run Config and the Jar artifact?
Thanks
*** UPDATE ***
I still get the above error message – even when creating a very basic OptaPlanner project.

Here’s what I run with Maven:
mvn clean compile package java -jar ./target/foo-jar-with-dependencies.jar
Note: I’m using openjdk-17.0.2
java --version openjdk 17.0.2 2022-01-18 OpenJDK Runtime Environment (build 17.0.2+8-86) OpenJDK 64-Bit Server VM (build 17.0.2+8-86, mixed mode, sharing)
It still runs fine within IntelliJ’s system, but from Maven it just throws the above error.
Also, here’s my solverConfig.xml for reference.
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<solver xmlns="https://www.optaplanner.org/xsd/solver">
<solutionClass>org.acme.domain.MySolution</solutionClass>
<entityClass>org.acme.domain.Visit</entityClass>
<scoreDirectorFactory>
<constraintProviderClass>org.acme.solver.MyConstraintProvider</constraintProviderClass>
</scoreDirectorFactory>
<termination>
<millisecondsSpentLimit>2000</millisecondsSpentLimit>
</termination>
</solver>
And my Main.kt file:
object Main {
lateinit var solverFactory: SolverFactory<MySolution>
lateinit var solver: Solver<MySolution>
lateinit var scoreManager: ScoreManager<MySolution, SimpleLongScore>
@JvmStatic
fun main(args: Array<String>) {
solverFactory = SolverFactory.createFromXmlResource("solverConfig.xml")
solver = solverFactory.buildSolver()
scoreManager = ScoreManager.create(solverFactory)
}
}

Answer
An answer to another question suggests you need an extra artifact in your project. Technically, optaplanner-core module brings it, but the scope is runtime – so that dependency may not show up in the JAR with dependencies. (?) You will need to include it yourself; you can confirm that by checking mvn dependency:tree in your project.
That said, I am not sure why we use the runtime scope here. Maybe we need to re-evaluate.
Also, seeing as you are using an uberjar, I’m going to point to another uberjar-related question to perhaps pre-empt more struggle.
