You can reproduce the issue by compiling java modules with `mvn clean package`.

Since the code is generated by `protobuf` and it would be better to find a way to dismiss the warning.

The warnings are from the maven-javadoc-plugin when building the hybridse-proto module. Look at the generated Java code in java/hybridse-proto/src/main/java/com/_4paradigm/hybridse/tablet/Tablet.java. Investigate the protobuf configuration or maven plugin settings to suppress javadoc warnings for generated code. Run `mvn clean package` to reproduce, then check the pom.xml for javadoc plugin configuration.
