Not a runnable code in IntelliJ (Building a scheduling app with Quarkus and Timefold)

[jerome1968]

I followed the steps to "Build an AI-powered scheduling app with Quarkus and Timefold" but the Run menu option in the IntelliJ IDE is not available to me ("The file in the editor is not runnable"). Did I miss something?

I followed the steps described in this video: https://www.youtube.com/watch?v=QMgUxw4Kpb4&t=51s until 9 mn 13s. I am not able to run the app.

Here is the code of the GreetingResource java class and the app is expected to run at: localhost:8080/hello

package org.acme;
import ai.timefold.solver.core.api.solver.SolverManager;
import jakarta.inject.Inject;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;

import java.time.Duration;
import java.util.List;
import java.util.concurrent.ExecutionException;

@path("/hello")
public class GreetingResource {
@Inject
SolverManager<Schedule, String> solverManager;

@GET
@Produces(MediaType.APPLICATION_JSON)
public Schedule hello() throws ExecutionException, InterruptedException {
    Schedule problem = new Schedule(
            List.of(new Inspection("01", Duration.ofHours(10)),
                    new Inspection("02", Duration.ofHours(20)),
                    new Inspection("03", Duration.ofHours(10)),
                    new Inspection("04", Duration.ofHours(30)),
                    new Inspection("05", Duration.ofHours(20))));

    Schedule solution = solverManager.solve("job 1", problem).getFinalBestSolution();
    return solution;
}

}

Hey @jerome1968, welcome to the fold!

If you're asking why the application is not runnable in IntelliJ, are you sure you've got the Quarkus plugin installed and enabled?

Alternatively, you may want to check out our quickstarts, which are pre-made and therefore should work out of the box.

Hey @triceo, good news: everything works fine now!
The problem was the lack of the extension RESTEasy Classic (quarkus-resteasy).
Thank you for your support.

Hi @triceo , could you give me some hints on the process to update the Timefold solver lib used by my App when I notice in the Quarkus documentation that the Timefold solver has been updated? Thank you.

Hi @jerome1968, nice to have you hare.

The simplest is probably to update your pom.xml file or gradle file.
We release a new version about once a month, all of them should be drop-in and no client side changes are required, unless if you want to use any of the new features ofcourse.

Thank you for your answer @TomCools !
So it means that I just have to update the version tag in the pom.xml file and the application will be recompiled with the corresponding version of Timefold solver. If so, it is very easy, indeed!
