What is the difference between spring cloud config server exec.jar and .jar suffix

Question

We are currently using spring cloud config server spring-cloud-config-server-1.1.0.M2-exec.jar and would like to upgrade to the latest version. However, i've noticed that beyond 1.1.0.M2 version there's only standard jars and no exec.jar in Maven repo http://maven.springframework.org/milestone/org/springframework/cloud/spring-cloud-config-server/

Could someone please explain what the difference is? Will I be able to just substitute the exec one with the standard non exec one?

Thanks

The exec jar contains an executable version of the config server (as a Spring Boot application). The non-exec jar contains only the config server classes. So you can't just replace the exec jar with the other one. What you basically have to do is to create a basic Spring Boot application with the config server dependencies and the appropriate annotations (like in the example):

@SpringBootApplication
@EnableDiscoveryClient
@EnableConfigServer
public class ConfigServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConfigServerApplication.class, args);
    }
}
