 If you don't wish to re-generate the settings.gradle, build.gradle, and gradle-wrapper.properties files,
 add the flag `--no-gradle-generation`.
 This tool automatically excludes a set of android subdirectories, defined at dev/tools/bin/config/lockfile_exclusion.yaml.
 To disable this behavior, run with `--no-exclusion`.
 Running without exclusion.
