I am working on creating a REST API using Timefold for Quarkus and running it as a native build on Windows-based GraalVM.
I have implemented a POST method named /evaluate, which calculates scores instead of executing jobs. When running it with the mvn quarkus:dev command on the JVM, it works correctly. However, when executing the native build, an error occurs when the POST method is called.
@Operation(summary = "Calculate and return a score for the allocation schedule.")
@APIResponses(value = {
@APIResponse(
responseCode = "200",
description = "Schedule scores.",
content = @Content(mediaType = MediaType.APPLICATION_JSON, schema = @Schema(implementation = StaffScheduleEvaluationResponse.class))
),
@APIResponse(responseCode = "404", description = "Score not found.",
content = @Content(mediaType = MediaType.APPLICATION_JSON,
schema = @Schema(implementation = ErrorInfo.class))),
@APIResponse(responseCode = "500", description = "A problem occurred while processing the score.",
content = @Content(mediaType = MediaType.APPLICATION_JSON,
schema = @Schema(implementation = ErrorInfo.class)))
})
@POST
@Path("/evaluate")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public StaffScheduleEvaluationResponse getEvaluate(StaffSchedule problem) {
// Score Calculation
SolverFactory<StaffSchedule> actualSolverFactory = SolverFactory.createFromXmlResource("org/acme/staffscheduling/solverConfig.xml");
SolutionManager<StaffSchedule, HardMediumSoftScore> solutionManager = SolutionManager.create(actualSolverFactory);
ScoreAnalysis<HardMediumSoftScore> scoreAnalysis = solutionManager.analyze(problem);
ScoreAnalysisResult scoreAnalysisResult = generateScoreAnalysis(scoreAnalysis, problem);
return new StaffScheduleEvaluationResponse(
scoreAnalysis.score(),
scoreAnalysisResult
);
}

If anyone could help me resolve this issue, I would greatly appreciate it.
After the revision:
By following the advice you kindly provided, I was able to resolve the issue with the following adjustments.
quarkus.timefold.solver.score-director-factory.constraint-provider-class (in application.properties)
<scoreDirectorFactory>, <solutionClass> and <entityClass> (in solverConfig.xml)
SolverManager<StaffSchedule, String> solverManager;
SolutionManager<StaffSchedule, HardMediumSoftScore> solutionManager;
SolverFactory<StaffSchedule> solverFactory;
@Inject
public StaffScheduleResource(SolverManager<StaffSchedule, String> solverManager, SolutionManager<StaffSchedule, HardMediumSoftScore> solutionManager, SolverFactory<StaffSchedule> solverFactory) {
this.solverManager = solverManager;
this.solutionManager = solutionManager;
this.solverFactory = solverFactory;
}
/** Attempt 1: To use the CDI proxy of solverFactory, the following line was removed: */
// SolverFactory<StaffSchedule> actualSolverFactory = SolverFactory.createFromXmlResource("org/acme/staffscheduling/solverConfig.xml");
// SolutionManager<StaffSchedule, HardMediumSoftScore> solutionManager = SolutionManager.create(actualSolverFactory);
/** Attempt 2: A ClassCastException occurred when attempting to use the CDI proxy of solverFactory with SolutionManager.create. This line turned out to be unnecessary.*/
// SolutionManager<StaffSchedule, HardMediumSoftScore> solutionManager = SolutionManager.create(solverFactory);
ScoreAnalysis<HardMediumSoftScore> scoreAnalysis = solutionManager.analyze(problem);

That SolverFactory.createX call is weird. In quarkus, you should just @Inject SolverManager, SolutionManager or SolverFactory, if the timefold-solver-quarkus dependency is in your pom.xml. Let the timefold quarkus extension figure out how to create those.
I suspect that StaffScheduleResource.java line 647 isn't even using org/acme/staffscheduling/solverConfig.xml! Otherwise the error message makes no sense at all.
