Java code has many errors after the protoc compiled

Question

Why does the class generated by protoc generates the following compile errors?

Description Resource Path Location Type Cannot override the final method
from GeneratedMessage AddressBookProtos.java
/monitor/src/main/resources/com/example/tutorial line 102 Java Problem
Cannot override the final method from GeneratedMessage
AddressBookProtos.java /monitor/src/main/resources/com/example/tutorial
line 339 Java Problem Cannot override the final method from
GeneratedMessage AddressBookProtos.java

and my pom.xml::

<dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>3.8.1</version>

You may have the same problem as here http://stackoverflow.com/a/16146992/980776. Try to use protobuf-java version 2.5.0. — dmitrievanthony, Apr 29 '15 at 07:36
compiler libprotoc 2.6.1 must be with protoc2.6.1jar..thanks a lot — topCoder, Apr 29 '15 at 08:26
I've got something similar with the protobuf maven reference and the protoc versions matching at 3.14.0 — Neil Benn, Jan 20 '21 at 14:55

I don't think that your pom file is relevant here. The error messages are quite clear: you cannot override the final method. The word final is used for the methods to avoid overriding, so removing final should help, otherwise include the code.
