FAILED: returned non-zero exit status 1 when trying to rename methods or classes #147

Hi.

I'm trying to change at least the methods and fields but when I try to rename methods it always returns status 1.

Resuming, with ClassRename or MethodRename fails. Only FieldRename it pass.

Also I tried with signature or without but the result is the same.

Here's an example: sudo docker run --rm -it -u $(id -u):$(id -g) -v "${PWD}":"/workdir" obfuscapk -o RandomManifest -o FieldRename -o MethodRename -o Rebuild -o NewAlignment -o NewSignature ./app.apk -p

The output is: `Renaming field declarations: 100%|█████████████████████████████████████████████████████████████████████████████████████████████████████████|[00:00<00:00, 1228.18file/s] Renaming field declarations: 100%|█████████████████████████████████████████████████████████████████████████████████████████████████████████|[00:00<00:00, 2587.13file/s] Renaming field declarations: 100%|█████████████████████████████████████████████████████████████████████████████████████████████████████████|[00:04<00:00, 1967.24file/s] Renaming field declarations: 100%|█████████████████████████████████████████████████████████████████████████████████████████████████████████|[00:03<00:00, 2132.55file/s] Renaming field declarations: 100%|█████████████████████████████████████████████████████████████████████████████████████████████████████████|[00:02<00:00, 2267.69file/s] Processing multidex: 100%|████████████████████████████████████████████████████████████████████████████████████████████████████████████████████|[00:11<00:00, 2.38s/dex] Renaming field references: 100%|███████████████████████████████████████████████████████████████████████████████████████████████████████████|[00:12<00:00, 1983.04file/s] Renaming method declarations: 100%|████████████████████████████████████████████████████████████████████████████████████████████████████████|[00:08<00:00, 2931.77file/s] Renaming method invocations: 100%|█████████████████████████████████████████████████████████████████████████████████████████████████████████|[00:11<00:00, 2059.52file/s] Running obfuscators (Rebuild): 50%|█████████████████████████████████████████████████▌ |[01:16<01:15, 25.20s/obfuscator]20/10/2022 19:38:15> [ERROR][obfuscapk.tool.Apktool][build()] Error during build command: I: Using Apktool 2.6.0 I: Smaling smali folder into classes.dex...
