In this post we will see how to fix Java.lang.classnotfoundexception exception.
The java.lang.ClassNotFoundException with the message$TimeConversion typically occurs when the Java Virtual Machine (JVM) cannot find a class that your code is trying to use. In this case, it’s specifically looking for the TimeConversion class within the package, but it cannot locate it.

Let’s see how to fix Java.lang.classnotfoundexception error.

To fix the java.lang.ClassNotFoundException for$TimeConversion, we need to ensure that the required Avro libraries and their dependencies are correctly configured in your Java project’s classpath.

  1. Download Avro Library: First, download the Apache Avro library (JAR files) from the official website ( Make sure we download the correct version that includes the TimeConversion class.
  2. Add JAR Files to Your Project:

If we are using an IDE like Eclipse or IntelliJ IDEA, we can usually add JAR files to your project by right-clicking on the project, selecting “Build Path” or “Add External JARs,” and then navigating to the Avro JAR files that are downloaded.

If we are using a build tool like Maven or Gradle, you can specify the Avro dependency in our project configuration file: For Maven (add this to your pom.xml):


In case of Gradle

dependencies {
    implementation group: 'org.apache.avro', name: 'avro', version: 'your-avro-version'
  1. Rebuild and Run Your Project: After adding the Avro library to your project, rebuild your project to ensure the Avro JAR files are included in the classpath. Then, run your application again.

By following these steps, you should resolve the java.lang.ClassNotFoundException for$TimeConversion. Ensure that you have the correct Avro library version, and that your project’s build configuration is correctly set up to include the necessary dependencies.

Hope this will help.

That’s all about how to fix Java.lang.classnotfoundexception exception.
