hi all, I have a library, let's call it Lib, which uses Jackson, and a client which uses Lib. If I try to make any calls in Lib which involve some Jackson calls under the hood, I get some exceptions related to Jackson not being able to load modules. The only way to fix this is to also include Jackson as a dependency in my client application, even tho it's already a dependency in Lib. Am I missing something here?

the specific error I get: Exception in thread "main" java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.introspect.AnnotatedConstructor.getType()Lcom/fasterxml/jackson/databind/JavaType;

i think it may have something to do with another dependency shipping with a lower version of Jackson which breaks some compatibility, so explicitly specifying the version of jackson I want to use fixes the issue

It sounds like an implementation vs api configuration issue. Can you try to declare your library’s dependency on Jackson using api("<group>:<module:<version>") as opposed to implementation("<group>:<module:<version>")

if you think its a version mismatch that should be easy to test with a call to ./gradlew dependencies
