Compile a Java Application to leverage Kafka

Question

I am using the following to write a message producer:

Maven
Java 1.8
Ubuntu

My pom.xml file has this entry from http://kafka.apache.org/documentation.html#theproducer

        <dependency>
            <groupId>org.apache.kafka</groupId>
            <artifactId>kafka-clients</artifactId>
            <version>0.8.2.0</version>
        </dependency>

When I issued here is what my HelloWorld.java app looks like:

import kafka.javaapi.producer.Producer;

public class HelloWorld
{
        public static void main(String args[])
        {
                int x = 4;
                System.out.println("hello world");
        }
}

I then compile using Maven.

mvn compile

But I get the following error.

[ERROR] /home/azureuser/test-application/src/main/java/HelloWorld.java:
            [6,30] package kafka.javaapi.producer does not exist

Does anyone know what is missing?

Any help appreciated.

In your IDE, does it say this package exists in the project? — Peter Lawrey

incorrect import : it should be import org.apache.kafka.clients.producer.Producer; — anurag gupta

Based on my search on Maven Central it looks like your defined dependency is wrong.

Look into your .m2 repository and find the jar (.m2/repository/org/apache/kafka/kafka-clients-0.8.2.0.jar) file, and you will see that the import should be:

import org.apache.kafka.clients.producer.Producer;

I think the correct import should be org.apache.kafka.clients.producer. Check the packages section at the bottom here
