Aligns the junit-sample's direct
jackson-databinddependency with the Jackson version current Imposter releases are built against, so the example's runtime classpath uses a single, consistent Jackson.Summary
jackson-databindfrom 2.18.2 to 2.21.0 injunit-sample/pom.xmlImplementation details
Imposter publishes against Jackson 2.21.0. The sample's direct
jackson-databinddeclaration was the nearest match in Maven's nearest-wins resolution, so it kept pullingjackson-annotations2.18 onto the test classpath. That conflicted withjackson-module-kotlin2.21 (which callsJsonProperty.isRequired()expecting the newOptBooleanreturn type introduced in 2.19+), producingNoSuchMethodErrorat engine startup and breaking theExamplesjob in imposter-jvm-engine's CI. Bumping the sample's direct version to 2.21.0 lets nearest-wins agree with Imposter on a single Jackson version.The example's
PetService.javausesObjectMapperfromsrc/main/java, so the dependency itself must stay (compile-scope) — only the version needs to track the engine.
