Seeing the below error when using current savers spring boot starter implementation (v 2.0.2)

My POM has

            <version>2.0.2</version>
        </dependency>

Application.yml file has

javers:
  mapping-style: BEAN

Here's my custom AuthorProvider that I am using...

@Component
public class JaversSpringAuthorProvider implements AuthorProvider {

    @Override
    public String provide() {
        UserPrincipal principal = (UserPrincipal) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
        if (principal == null) {
            return AuthoritiesConstants.SYSTEM_USER;
        }
        return String.valueOf(principal.getUserKey());
    }
}

I'm also using HikariCP for Datasource creation

Some startup logs before the error is thrown are...

The Repository has been annotated with @JaversSpringDataAuditable and no other code changes have been made to integrate with Javers. I made the changes as suggested in http://javers.org/documentation/spring-boot-integration/ so please let me know if I am missing something here.

@kaustubhkeshav please follow the Guidelines for Bug Reporting
https://github.com/javers/javers/blob/master/CONTRIBUTING.md#guidelines-for-bug-reporting
and contribute a failing test case.

looks like this is a problem with visibility of JaversTransactionalDecorator, but we need a test to prove it.

[kaustubhkeshav]

Seems like this is happening if we have the below dependency on our class path. Should be fairly easy to replicate.

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
            <version>1.1.0.RELEASE</version>
        </dependency>

[bartoszwalacik]

fixed in release 2.0.3

@ravindrapawar I have no idea why you are posting here, this issue is totally unrelated to your exception. Btw try to read and understand stack traces before posting them on github and calling for help.

Factory method 'javers' threw exception; nested exception is com.mongodb.MongoTimeoutException: Timed out after 30000 ms while waiting to connect

You are trying to connect to MongoDB, but on your machine there is no mongo server at localhost:27017.
