Quarkus + Kogito build error: java.lang.IllegalStateException: Cannot find class info in jandex index for java.time.LocalDateTime

Question

I have a multi-module Maven project that uses Quarkus and Kogito, with MongoDb persistence. The module with the Kogito process definition is using beans from another module. One of the beans has a property of type java.time.LocalDateTime.

public class SomeBean {
    ...
    private LocalDateTime changeDatetime;

    public SomeBean() {
    }

    ...
    public LocalDateTime getChangeDatetime() {
        return changeDatetime;
    }

    public void setChangeDatetime(LocalDateTime changeDatetime) {
        this.changeDatetime = changeDatetime;
    }
}

When running a @QuarkusTest for a process, I get the following error:

io.quarkus.builder.BuildException: Build failure: Build failed due to errors
        [error]: Build step org.kie.kogito.quarkus.processes.deployment.ProcessesAssetsProcessor#postGenerationProcessing threw an exception: java.lang.RuntimeException: Error while generating proto for model class com.example.PrcessInputBean Cannot find class info in jandex index for java.time.LocalDateTime

I tried solutions from: How to create a Jandex index in Quarkus for classes in a external module but it does not work.

I noticed that if I remove the java.time.LocalDateTime property from the bean, the test is running fine. How can I configure Jandex to index java.time.LocalDateTime and get rid of this error?

Answer 1

support for java.time.LocalDateTime has been added to Kogito recently and will be available in the next release, 1.18.0.Final, see https://issues.redhat.com/browse/KOGITO-6756
