Maven build failing with PKIX path building failed

Hello, I am trying to build my kafka streams application and the maven build fails with this error. Any idea how I can resolve this.

Could not resolve dependencies for project com.pwc.orders:kafkastreams-poworkflowjsonprocessing-avro:jar:1.0: Failed to collect dependencies at io.confluent:kafka-avro-serializer:jar:6.2.0 : Failed to read artifact descriptor for io.confluent:kafka-avro-serializer:jar:6.2.0: Could not transfer artifact io.confluent:kafka-avro-serializer:pom:6.2.0 from/to confluent (Index of maven): transfer failed for https://packages.confluent.io/maven/io/confluent/kafka-avro-serializer/6.2.0/kafka-avro-serializer-6.2.0.pom: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target → [Help 1]

Seems to be there: https://packages.confluent.io/maven/io/confluent/kafka-avro-serializer/6.2.0/

Can you try as an alternative: https://mvnrepository.com/artifact/io.confluent/kafka-avro-serializer
