Description

When I tried to compile flink-sql-connector-kafka with Java 17 and using profile -Pjava17 -Pjava17-target:

 

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:3.2.4:shade (shade-flink) on project flink-sql-connector-kafka: Error creating shaded jar: Problem shading JAR flink-connectors/flink-connector-kafka/flink-connector-kafka/target/flink-connector-kafka-3.1-SNAPSHOT.jar entry org/apache/flink/streaming/connectors/kafka/FlinkKafkaProducerBase.class: java.lang.IllegalArgumentException: Unsupported class file major version 61 

maven-shade-plugin supports Java 17 starting from 3.3.0 (see MSHADE-407). We need to set the version of maven-shade-plugin to at least 3.3.0 for profile java17 in flink-connector-parent pom.
