我正在尝试使用Java 11.0.2编译（mvn pacakge）KSQL v5.3.1。
我在编译ksql-common时遇到以下错误：
[INFO] --- maven-surefire-plugin:2.21.0:test (default-test) @ ksql-common ---

java.lang.AssertionError:
Expected: (an instance of io.confluent.ksql.util.KsqlException and exception with message a string containing "cannot be cast to org.apache.kafka.streams.processor.TimestampExtractor")
but: exception with message a string containing "cannot be cast to org.apache.kafka.streams.processor.TimestampExtractor" message was "Cannot override default timestamp extractor: class io.confluent.ksql.util.timestamp.TimestampExtractionPolicyFactoryTest cannot be cast to class org.apache.kafka.streams.processor.TimestampExtractor (io.confluent.ksql.util.timestamp.TimestampExtractionPolicyFactoryTest and org.apache.kafka.streams.processor.TimestampExtractor are in unnamed module of loader 'app')"
Stacktrace was: io.confluent.ksql.util.KsqlException: Cannot override default timestamp extractor: class io.confluent.ksql.util.timestamp.TimestampExtractionPolicyFactoryTest cannot be cast to class org.apache.kafka.streams.processor.TimestampExtractor (io.confluent.ksql.util.timestamp.TimestampExtractionPolicyFactoryTest and org.apache.kafka.streams.processor.TimestampExtractor are in unnamed module of loader 'app')
帮助深表感谢；谢谢！
最佳答案
您可能想在Github上报告该问题，但是我想包装说明中包括跳过测试。
mvn package -DskipTests
否则，请随意下载Confluent Platform 5.3.1，仅配置和使用ksql属性，或使用预构建的Docker映像。
