}
getting error
Unable to load class 'com.datastax.oss.driver.api.mapper.entity.naming.GetterStyle'.
i tried to interaction with different project also but still not able to solve issue
. for testing part i added library mappstruct which is generation code on compile time

Answer 1

With drivers 4x+, you need to declare an annotation processor for the mappers code to be generated at build time.
Gradle file
dependencies {
annotationProcessor group: 'com.datastax.oss', name: 'java-driver-mapper-processor', version: javaDriverVersion
compile group: 'com.datastax.oss', name: 'java-driver-mapper-runtime', version: javaDriverVersion
}
