Unable to use generated Classes from Avro

Question

I must be missing something in my maven file. When generating classes with avro-maven-plugin, I want to use them in a class in the same project. I am able to generate the classes in the target/classes , but cannot use them in classes living in source/main/java , the compiler does not find them.

   <plugin>
      <groupId>org.apache.avro</groupId>
         <artifactId>avro-maven-plugin</artifactId>
         <version>1.8.2</version>

                  <goal>schema</goal>
               </goals>
            </execution>
        </executions>
      </plugin>
