Override/Upgrade jackson dependency in latest Dropwizard

[Nadav Lavy]

Hello

I'm using Dropwizard 2.0.22 (latest at the time of this writing).

It depends on fairly old Jackson - 2.10.5 (latest is 2.12.3).

This creates an issue in my project where we need to use features from latest Jackson (and in general be able to upgrade to its latest).

Can I safely override the Jackson version Dropwizard depends on?

Does it use it internally for things that might break if I do?

Thanks!

Hi Nadav,

Can I safely override the Jackson version Dropwizard depends on?

Does it use it internally for things that might break if I do?

Yes, it should just work and yes, Dropwizard is using Jackson internally, for example for parsing the configuration files and to serialize/deserialize JSON in JAX-RS resources.

Here's the PR which updated Jackson (first 2.11.x, then 2.12.x) for the Dropwizard 2.1.x branch:

https://github.com/dropwizard/dropwizard/pull/3229

As you can see in the PR there weren't many changes required. ;-)

Cheers,

Jochen

Thanks for the detailed info Jochen!

I tried upgrading and got multiple errors.

At that point I abandoned the effort and decided its best wait for dw 2.1.x to be out of beta, (and guicy support will be added as well).
