Quarkus Kogito build error: java.lang.IllegalStateException: Cannot find class info in jandex inde-CodePudding

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

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?

CodePudding user response：

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

CodePudding user response：

java.time is included in JRE since 8 AFAIK.

Are you sure you are running this with Java 8?
