Spring Boot Docker Compose reports exit code 0 on application run failed about spring-boot HOT 2 CLOSED

You haven't mentioned it, by I can tell from the log output that, in example 1, you're using spring-boot-devtools. The problem that you're seeing is a duplicate of #28541.

I cannot reproduce the behavior you have described in example 2, either with or without spring-boot-devtools on the classpath. If you would like us to spend some more time investigating, please spend some time providing a complete yet minimal sample that reproduces the problem. You can share it with us by pushing it to a separate repository on GitHub or by zipping it up and attaching it to this issue.

You're right. Removing spring-boot-devtools fixes issue in example 1.

Regarding example 2:
After lots of debugging it seems that it was not related to Spring but an issue with the Maven Surefire plugin version 3.0.0-M4.
I have upgraded to latest version 3.2.5 and now the Docker Compose error is correctly reflected in the exit code.

Issue is resolved.
