MartijnVisser opened a new pull request, #29434: URL: https://github.com/apache/flink/pull/29434
## What is the purpose of the change Replace protoc-jar-maven-plugin and the archived xolstice protobuf-maven-plugin with [ascopes/protobuf-maven-plugin](https://github.com/ascopes/protobuf-maven-plugin) 3.10.3, instead of the 0.6.1 bump the ticket asked for. This removes the workaround from FLINK-11427 and FLINK-19616 and lets platforms without a protoc on Maven Central build. Nothing that fails in CI today is fixed by this. ## Brief change log - Configured once in the root pom. 4.0.0 and later require Java 17, and Flink still builds on JDK 11. - `os-maven-plugin`, the `build-helper` executions, `checkStaleness` and the proto timestamps in `unpack_build_artifact.sh` are removed. - `-Dprotobuf.compiler.version=PATH` uses a local protoc, e.g. on riscv64. - flink-parquet's test protos move to `src/test/proto`, dropping their rat exclude. ## Verifying this change This change is already covered by existing tests. In addition, compared against master: - Generated sources are byte-identical in all three modules on JDK 11 and 17. The flink-python jar is unchanged (all 21,467 entries). - flink-protobuf and flink-parquet `verify` give the same test counts. - With exec bits stripped from `target/`, master fails with `error=13, Permission denied`, while this branch regenerates. `mvn compile -pl flink-python` on its own now needs the test-jars flink-python depends on, as flink-parquet already did. Switching back to a branch without this change needs a `clean`, otherwise flink-python can hit a duplicate `FlinkFnApi` class. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): yes, a build plugin only - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no - The serializers: no - The runtime per-record code paths (performance sensitive): no - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? no - If yes, how is the feature documented? not applicable --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes (please specify the tool below) Generated-by: Claude Code (Claude Opus 5.5) -- This is an automated message from the Apache Git Service.
