Schema registry plugin validate goal fails for new schemas

[dorianpavetic]

When having empty schemas in the Schema Registry, or just try to add new schemas and execute io.confluent:kafka-schema-registry-maven-plugin:7.8.0:validate, I get "subject not found exception". Same thing happens for test-compatibility.

Why wouldn't it just return that schema is valid/compatible if it is new? This makes it impossible to use CI/CD without manually pushing schemas to the Schema registry.. But at this point, CI/CD makes no sense as schemas are already there.

[ERROR] Could not parse Avro schema
java.lang.RuntimeException: io.confluent.kafka.schemaregistry.client.rest.exceptions.RestClientException: Subject 'tenant-id' not found. io.confluent.rest.exceptions.RestNotFoundException: Subject 'tenant-id' not found.
io.confluent.rest.exceptions.RestNotFoundException: Subject 'tenant-id' not found.

This is my config:

<plugin>
                <groupId>io.confluent</groupId>
                <artifactId>kafka-schema-registry-maven-plugin</artifactId>

                </configuration>
            </plugin>
