I had the same problem, it seems that:
com.fasterxml.jackson.core
jackson-databind
2.9.0
had dependency to jackson-annotations in version 2.8.0 which crashed somehow with my other jackson dependencies.
after modifying the dependency as follows:
com.fasterxml.jackson.core
jackson-databind
com.fasterxml.jackson.core
jackson-annotations
and adding explicit dependency on:
com.fasterxml.jackson.core
jackson-annotations
2.9.0
problem was solved for me :)
