This pull request updates the Spark job server build configuration to enable multi-release JAR support. It also cleans up a previous workaround related to gradle caching, streamlining the build process for the shadow jar.

Highlights

• Multi-Release Manifest Attribute: Added the 'Multi-Release' attribute to the Spark job server jar manifest to support multi-release JAR functionality.

Code Review

This pull request modifies the shadowJar task configuration in spark_job_server.gradle by removing a Gradle cache workaround and adding a Multi-Release manifest attribute. The reviewer suggests splitting these logically distinct changes into separate pull requests to improve commit history and maintainability.

[gemini-code-assist]

This pull request combines two logically separate changes:

1. Removing the Gradle cache workaround (outputs.upToDateWhen { false }).
2. Enabling the Multi-Release manifest attribute.

Combining unrelated changes in a single pull request can make the commit history harder to follow and complicates tasks like reverting or cherry-picking commits. It is recommended to submit separate pull requests for each distinct logical change.

Please consider splitting these changes into two separate pull requests.
