Create jakarta artifact replacing javax.json with jakarta.json

[fwiesweg]

Fixes #6.

This is an alternative solution to the problem, using postprocessing of the class files using the maven-shade-plugin as applied by jackson-jaxrs-providers.

Thank you! That looks good, and I'd be happy to merge it.

Before merging there is just one process thing: I'd need a CLA (unless I have gotten one earlier at some point -- only needs to be done once before the first merged PR).
CLA doc is here:

https://github.com/FasterXML/jackson/blob/master/contributor-agreement.pdf

and the usual mechanism is to print it, fill & sign, scan/photo, email to info fasterxml dot com.
Once I get it I'll store it and merge this PR.

Looking forward to merging!

CLA received, merged. Will backport in 2.12 branch for 2.12.2.

[cowtowncoder]

Alas, need to revert; 2.12.2 release broke due to... something.

[fwiesweg]

Sure, I'm not in a hurry to get this out of the door. Anything I can do?

@fwiesweg I think we are ok -- I ended up instead merging #10 to get the similar end result, but instead of using classifier, there's separate artifact (jackson-datatype-jakarta-jsonp). There's now some code duplication but number of classes is small so I am not very worried; and for 3.0 at least we may want to drop jsr-353 module (TBD what to do with 2.x, at least after 2.13).

Still need to figure out what's wrong with classifier approach as that is needed for JAX-RS, but in short term I think this repo will get by without solving that. I do hope 2.12.2/jackson-datatype-jsr353 artifact can be corrected by sonatype admins tho.
