Exclude guava, jackson-core, jackson-databind from jib-core

mentioned were shaded. However, after introducing Jib, those
transitive dependencies became part of the API. For that reason,
currently, those are not shaded.

In 1.17.6:

Currently:

The other alternative is switching from provided to implementation

Could you please clarify this one? We might have to move Jib to a module if that's the case.

ohhh... I think I finally understand what happened! The shading logic does not consider provided's transitive dependencies as provided too and shades them.

An easy workaround would be to exclude all non-jib transitive dependencies of jib and re-add Jib as testImplementation (for testing)

[eddumelendez]

ok. Thanks @bsideup !
