Hello,
I understand that you are having an error in a test[1] <https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/util/Assert.html>, getting the error at org.springframework.util.Assert.notNull(Assert.java:201). To provide you with more relevant information, are there line numbers and your code that you can add? The error by itself can mean several things. I’ve included Stackoverflow articles[2 <https://stackoverflow.com/questions/42937577/unable-to-find-main-class-with-maven-on-spring-boot-project-in-eclipse> ][3 <https://stackoverflow.com/questions/53582515/spring-boot-app-on-google-app-engine-unable-to-find-main-class/53583544>] with a similar message and I hope it helps but if it does not, please provide the information. Google Groups is meant for general discussions about Google products and services. It seems to me that this is more of a technical issue, which is appropriate to Stackoverflow but we will wait and see how this conversation progresses.
