Review Comment:
The environment variables CPPFLAGS and LDFLAGS are set but not exported.
These should be exported to ensure they are available to the gradle build
process: `export CPPFLAGS=...` and `export LDFLAGS=...`.
```suggestion
export CPPFLAGS="-I${PROTOBUF_ROOT}/src"
export LDFLAGS="-L${PROTOBUF_ROOT}/src/.libs"
```

Review Comment:
The prerequisite comment lacks specific version requirements. Consider
specifying the minimum Gradle version and compatible JVM versions needed for
building gRPC Java to help users avoid compatibility issues.
```suggestion
# Pre-req: Manually install Gradle (version 7.0 or higher) and a compatible
JVM (JDK 8 or higher) as required by gRPC Java v1.71.0. See
https://github.com/grpc/grpc-java/blob/v1.71.0/README.md for details.
