Ok great, thanks. What are the other required dependencies?
For exmaple, log4j seems needed:
Caused by: java.lang.NoClassDefFoundError: org/apache/log4j/Logger
at kafka.utils.Logging$class.logger(Logging.scala:24)
at
kafka.utils.VerifiableProperties.logger(VerifiableProperties.scala:23)
at kafka.utils.Logging$class.info(Logging.scala:66)
at kafka.utils.VerifiableProperties.info(VerifiableProperties.scala:23)
at
kafka.utils.VerifiableProperties.verify(VerifiableProperties.scala:180)
at kafka.producer.ProducerConfig.<init>(ProducerConfig.scala:57)
However adding the following dependencies are not compatible
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.5</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.0.13</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>1.0.13</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>log4j-bridge</artifactId>
<version>0.9.7</version>
</dependency>
Because is produces this error:
