Androi Packaging obfuscation report the same input jar [*.jar] is specified twice error

The same input jar [*.jar] is specified twice error after upgrading to a higher version of the Android SDK, resulting in confusion failure unable to package a new version of the Proguard package app

After a day of tossing people to collapse, and eventually I found a solution. Here's how to fix it:

1. Open Proguard-project.txt
2. Insert # into #-libraryjars Xxxx.jar before all-libraryjars or delete directly

Cause analysis, it is possible that the high-version SDK has already added the jar in the Lib directory to the packaging script by default when the code is obfuscated by Proguard, so it does not need to be added manually.
