Usage

As a library

public class SomeRandomDeobfuscator {
    public static void main(String[] args) throws Throwable {
        Configuration config = new Configuration();
        config.setInput(new File("input.jar"));
        config.setOutput(new File("output.jar"));
        config.setPath(Arrays.asList(
                new File("C:\\Program Files\\Java\\jdk_8\\jre\\lib\\rt.jar"),
                new File("C:\\Program Files\\Java\\jdk_8\\jre\\lib\\jce.jar"),
                new File("C:\\Program Files\\Java\\jdk_8\\jre\\lib\\ext\\jfxrt.jar"),
                new File("C:\\Program Files\\Java\\jdk_8\\lib\\tools.jar")
        ));
        config.setTransformers(Arrays.asList(
                TransformerConfig.configFor(PeepholeOptimizer.class)
        ));
        new Deobfuscator(config).start();
    }
}

CLI

If you don't want to import the project, you can always use the command line interface.

Argument	Description
--config	The configuration file

You may specify multiple transformers, and they will be applied in the order given. Order does matter as sometimes one transformation depends on another not being present.

If you wish to use one of the default transformers, then you may remove the com.javadeobfuscator.deobfuscator.transformers prefix.

Here is a sample config.yaml:

input: input.jar
output: output.jar
transformers:
  - normalizer.MethodNormalizer:
      mapping-file: normalizer.txt
  - stringer.StringEncryptionTransformer
  - normalizer.ClassNormalizer: {}
    normalizer.FieldNormalizer: {}
