proguard

Work with ProGuard/R8 mapping files

Commands

sentry proguard uuid <path>

Compute the UUID for a ProGuard mapping file

Arguments:

Argument	Description
<path>	Path to the ProGuard mapping file

All commands support --json for machine-readable output and --fields to select specific JSON fields.

Examples

# Compute the UUID for a ProGuard/R8 mapping file
sentry proguard uuid ./app/build/outputs/mapping/release/mapping.txt

# Output as JSON (includes the file path)
sentry proguard uuid mapping.txt --json

Important Notes

• The UUID is deterministically derived from the mapping file contents — identical files always produce the same UUID. This is the same value Sentry uses to associate a mapping with obfuscated Android stack traces.
• This matches the UUID computed by the legacy sentry-cli proguard uuid command byte-for-byte.
