./gradlew -q calculateChecksums fails on checksum I want it to calculate

[retorquere]

When building Signal-Android, I'm getting signature verification failures, but when I try to recalculate the checksum, it fails on that same signature:

./gradlew -q calculateChecksums
signing.properties not found

Remove old checksums, run ./gradlew -q calculateChecksums and than paste new checksums in build.gradle
