描述

I would like to propose an option that could make the compiler fail if at least one warning is encountered, regardless of errors and exit with a non-zero exit code.

This could be a simple flags such as --fail-on-warnings or a more sophisticated setting like --error-level that could introduce more granular control, i.e. still exit with 0 if compilation failed with errors.

Use case for this is either a purist approach when no warnings are tolerated or code quality control CI job that verifies new code with --checks-only.

研究方向
The issue requests a command line flag to fail on warnings. Look at how existing flags are implemented in the compiler's main entry point, likely in CommandLineRunner.java or similar. Check the warning reporting mechanism and exit code handling. It may require adding an option to the Options class and modifying the compilation process to exit with non zero code when warnings are present.
