I guess the trouble is one of ,After everything I've tried, it's still the same.
please help me!
thanks!

No source files, tests, or entry points are identified in the report. Start by tracing realtime table creation through the Kafka topic metadata lookup and compare the broker, schema registry, and ZooKeeper settings shown in the configuration. Done means identifying the connection or configuration cause of the timeout and confirming that table creation succeeds.
