Obfuscating apks with the above mentioned obfuscators doesn't rebuild and gives error, this happens to me every time. Can you please give me a solution for that? I have tried my best but doesn't make any difference. Error:

It's a known issue (see https://github.com/ClaudiuGeorgiu/Obfuscapk/issues/19#issuecomment-613382276). I'm closing this as duplicate of #19, thanks for reporting.
