As mentioned in #9548, users currently use the kafka jar (`core` module) for integration testing and the current inlining behavior causes problems when the user's classpath contains a different Scala version than the one that was used for compilation. An example error: `java.lang.NoClassDefFoundError: scala/math/Ordering$$anon$7` We disable inlining of the `scala` package by default, but make it easy to enable it for those who so desire (a good option if you can ensure the scala library version matches the one used for compilation). While at it, we make it possible to disable scala compiler optimizations (`none`) or to use only method local optimizations (`method`). This can be useful if optimizing for compilation time during development. Verified behavior by running gradlew with `--debug` and checking the output after `[zinc] The Scala compiler is invoked with:` ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
