The pom value for scm:url is currently https://github.com:networknt/json-schema-validator.git. I think it should be https://github.com/networknt/json-schema-validator.git (/ instead of : after github.com). Probably check the scm:connection and scm:developerConnection as well.

I came across this when validating an SBOM that has json-schema-validator as a dependency, validation was failing on the vcs:url .
