I dockerized a spring boot application with Jib. When I run the docker image, I get this error. 

Caused by: java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/ObjectMapper

However, when I run java -jar application.jar then everything works fine.

What could be missing here?

  • Perhaps the jackson dependency is not being copied into the container due to a configuration issue. Could you file a bug on github and we can try to figure this out? https://github.com/GoogleContainerTools/jib/issues – loosebazooka Sep 20 '19 at 18:06

Check your java version - I had XML problems when I switched from Java 8 to Java 11.
