package com.google.protobuf.GeneratedMessageV3 does not exist

I clone https://github.com/brownsys/tracing-framework.git and run

mvn clean package install -DskipTests

It gives me error

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.3:compile (default-compile) on project pubsub: Compilation failure: Compilation failure:

How do I fix it?

@gqqnbig hi, I ran into a similar issue with protobuf when compiling browntracing. Did you have a fix for your problem in two years ago?
