io.vidocq.champollion:champollion-api

Pure re-exposition of the Jakarta specs (jakarta.json, jakarta.json.bind). Useful for consumer modules that don’t want to depend on an implementation.

io.vidocq.champollion:champollion-jsonp

JSON-P 2.1 implementation (parser, generator, object model, Patch / Pointer / Merge Patch). JsonProvider ServiceLoader.

io.vidocq.champollion:champollion-jsonb

JSON-B 3.0 implementation (Jsonb, JsonbBuilder, JsonbConfig). Depends on champollion-jsonp.

io.vidocq.champollion:champollion-codegen-apt

Annotation Processor (scope provided) generating JsonbBinding<T> at compile time.

io.vidocq.champollion:champollion-codegen-maven-plugin

champollion:generate Mojo bound to generate-sources; scans the classpath and invokes the APT on detected-but-unannotated types.

io.vidocq.champollion:champollion-bench

JMH — Parsson/Yasson/Jackson comparisons. No runtime scope.

io.vidocq.champollion:champollion-examples

Runnable examples.

io.vidocq.champollion:champollion-tck (out of reactor)

Official TCK runners JSON-P 2.1 + JSON-B 3.0. Invocation via run-official-tck-*.sh only.
