Hi,

I am not able to start Schema registry version 5.5.1 after building it. Kafka and Zookeeper are running getting error as

Looks like it's trying to search classes folder from D:\ka\schema-registry\target\classes but there is no such folder created in Parent level target folder.

I have tried with /d/kaf/apache-maven-3.6.3/bin/mvn exec:java -Dexec.mainClass=io.confluent.kafka.schemaregistry.rest.SchemaRegistryMain also with /d/kaf/apache-maven-3.6.3/bin/mvn exec:java

and also from Kafka-schema-registry/target as ./bin/schema-registry-start ./etc/schema-registry/schema-registry.properties from parent folder as ./bin/windows/schema-registry-start.bat ./config/schema-registry.properties

Do you need to build the project instead of downloading version 5.5.1?

Issue resolved.
