GitHub license Maven Package Maven Central Sonatype Nexus (Snapshots) GitHub stars

This is a service mapper for the ProGuard Java bytecode obfuscator.

It fixes the issue that files in the META-INF/services directory are not renamed or adapted to the new class names.

It replaces the original Jar file with a new one that contains the renamed services.

It consists of the following modules:

ProGuard Service Mapper CLI

For convenience, the service mapper can be run from the command line. Withouth any additional arguments, it will print help information.

Usage

$ java -jar proguard-service-mapper-cli-<version>.jar -i <input-file> -m <mapping-file>
