Remove `gradle-wrapper.jar` from source tree

[snazy]

The ASF Release Policy mentions that a source release should not contain compiled code. Jar files, like the gradle/wrapper/gradle-wrapper.jar file, are compiled code and should not be included in source releases. The Gradle build tool currently offers no way out-of-the box to run Gradle without having the wrapper jar in the source tree.

The repository demonstrates how to use Gradle without having the wrapper jar in the source tree.

This change adopts these changes for Apache Beam, and also

• Replace the deprecated gradle/gradle-build-action (repo is archived/read-only) with gradle/actions/setup-gradle
• Remove usage of the no longer necessary gradle/wrapper-validation-action (repo is archived/read-only)

Summary of Changes

Hello @snazy, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request modernizes the project's Gradle setup by removing the gradle-wrapper.jar from the source tree, aligning with ASF release guidelines. It introduces dynamic downloading and verification of the Gradle wrapper and updates GitHub Actions to use supported versions, enhancing build integrity and maintainability across the project's modules.

Highlights

• ASF Release Policy Compliance: The gradle-wrapper.jar file has been removed from the source tree to comply with Apache Software Foundation (ASF) Release Policy, which prohibits compiled code in source releases.
• Dynamic Gradle Wrapper Download: New gradlew-include.sh and gradlew-include.ps1 scripts have been introduced across various modules to dynamically download and verify the gradle-wrapper.jar and its checksum at runtime, ensuring integrity and policy compliance.
• GitHub Actions Update: Deprecated GitHub Actions (gradle/gradle-build-action and gradle/wrapper-validation-action) have been replaced with the current gradle/actions/setup-gradle action, improving maintenance and security for the build environment.
• Git Ignore Configuration: The .gitignore file has been updated to explicitly ignore gradle-wrapper.jar and its associated checksum files, preventing accidental re-inclusion into the repository.

Ignored Files

• Ignored by pattern: .github/workflows/** (1)
  • .github/workflows/code_completion_plugin_tests.yml

[kennknowles]

This seems like a mostly-benign change. It is also fine to simply exclude the jar from the source release zip (I'm actually surprised if this is not already the case).

The github action upgrades are nice and I don't think they require discussion - could they be decoupled and committed first?

[snazy]

@kennknowles sure! I've just rebased this branch and split it into 2 commits, the 1st commit is the content of #37064.
