Incorrect Dependency and Class Not found #5

Open yoga80 opened 6 years ago

yoga80 commented 6 years ago

Maven complained about the originally included dependency 

    <dependency>
        <groupId>org.apache.kafka</groupId>
        <artifactId>kafka-streams</artifactId>
        <version>0.10.3.0-SNAPSHOT</version>
    </dependency>

I updated to 

    <dependency>
        <groupId>org.apache.kafka</groupId>
        <artifactId>kafka-streams</artifactId>
        <version>0.11.0.0</version>
    </dependency>

However running the code throws

Caused by: java.lang.ClassNotFoundException: org.apache.kafka.streams.processor.TopologyBuilder at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 7 more

Any idea as to how to resolve?

I also received a similar same error whilst trying to run this program:
