Can run in Intellij, but jar file fails-CodePudding

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:

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)
    }
}

CodePudding user response：

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.
