JarCastingyaml-json-validator-maven-plugin
This maven plugin allows to validate yaml and json files to check that they are well formed and optionally validate against JSON schemas.
Both JSON and YAML files can be validated against a JSON schema. The library fge/json-schema-validator is internally used for this.
