             Summary: Implement Reproducible Builds for tika-grpc
                 Key: TIKA-4592
                 URL: https://issues.apache.org/jira/browse/TIKA-4592
             Project: Tika
          Issue Type: Sub-task
            Reporter: Nicholas DiPiazza


h2. Objective

Implement reproducible builds for the tika-grpc module to ensure bit-for-bit 
identical outputs across different build environments.

h2. Tasks

* Configure Maven properties for reproducible builds in tika-grpc/pom.xml
* Set project.build.outputTimestamp property
* Configure maven-jar-plugin for reproducible archive creation
* Configure maven-source-plugin for reproducible source archives
* Handle gRPC-generated code reproducibility
* Configure protobuf plugin for deterministic code generation

h2. Verification

* Build tika-grpc multiple times and verify checksums match
* Build on different machines/environments and verify reproducibility
* Verify gRPC generated code is deterministic
* Generate and verify .buildinfo file
* Document verification steps

h2. Acceptance Criteria

# tika-grpc JAR builds are reproducible
# gRPC generated code is deterministic
# Source archives are reproducible
# All timestamps are normalized
# buildinfo file is generated and validates successfully
