Hi Dave，I try to package the code from "spring-projects-experimental/spring-boot-thin-launcher/samples/multi/" and use "jar -jar application-0.0.1-SNAPSHOT.jar" after package. However, i got the error msg as follows:

I'm not sure whether the running statement is missing some parameters, resulting in a lack of correct POM dependencies. Hope to get your reply. Thanks!
