-----------------------------------
Summary: Use TestPlugins in ConnectorValidationIntegrationTest to
silence plugin scanning errors
Key: KAFKA-16068
URL: https://issues.apache.org/jira/browse/KAFKA-16068
Project: Kafka
Issue Type: Task
Components: KafkaConnect
Reporter: Greg Harris
The ConnectorValidationIntegrationTest creates test plugins, some with
erroneous behavior. In particular:
{noformat}
[2023-12-29 10:28:06,548] ERROR Failed to discover Converter in classpath:
Unable to instantiate TestConverterWithPrivateConstructor: Plugin class default
constructor must be public
(org.apache.kafka.connect.runtime.isolation.ReflectionScanner:138) [2023-12-29
10:28:06,550] ERROR Failed to discover Converter in classpath: Unable to
instantiate TestConverterWithConstructorThatThrowsException: Failed to invoke
plugin constructor
(org.apache.kafka.connect.runtime.isolation.ReflectionScanner:138)
java.lang.reflect.InvocationTargetException{noformat}
These plugins should be eliminated from the classpath, so that the errors do
not appear in unrelated tests. Instead, plugins with erroneous behavior should
only be present in the TestPlugins, so that tests can opt-in to loading them.
There are already plugins with private constructors and
throwing-exceptions-constructors, so they should be able to be re-used.
