java.lang.InknownClassChangeError : class com. typesafe.scalalogging.BaseLogger无法实现com.typesafe.scalalogging.Logger

Question

Error: java.lang.IncompatibleClassChangeError: class com.typesafe.scalalogging.BaseLogger can not implement com.typesafe.scalalogging.Logger**

我正在配置sink-influxDB。我收到上面的错误。我正在使用kafka-connect-influxdb-1.2.0.jar。其他支持的 jar 是

kcql-2.4.0.jar
influxdb-java-2.15.jar
scala-logging_2.11-3.9.0.jar
scala-logging-slf4j_2.11-2.1.2.jar
scala-logging-api_2.11-2.1.2.jar

com.typesafe.scalalogging.BaseLogger 来自 scala-logging-api_2.11-2.1.2.jar 实现 com.typesafe.scalalogging.Logger

这是异常堆栈

我已将 kafka connect jar 替换为 kafka-connect-influxdb-2.0.0-2.4.0-all.jar 并修改了工作属性以支持 String 类型的键和 AVRO 类型的值，如下所示

key.converter=org.apache.kafka.connect.storage.StringConverter
key.converter.schemas.enable=false

value.converter=io.confluent.connect.avro.AvroConverter
value.converter.schema.registry.url=http://localhost:8081
value.converter.schemas.enable=true

启动连接器时，抛出以下错误

Answer 1

尝试:

import com.typesafe.scalalogging.LazyLogging

而不是:

import com.typesafe.scalalogging.slf4j.LazyLogging

这应该可以修复您的以下错误:

class com.typesafe.scalalogging.BaseLogger can not implement com.typesafe.scalalogging.Logger, because it is not an interface
