Solution (transferred from: https://www.twblogs.net/a/5c95e18bbd9eee4a0d090cd5 ）：

1. From https://github.com/pxb1988/dex2jar Download the source code of dex2jar: dex2jar-2.x.zip

2. Recompile: enter the dex2jar-2. X directory and execute the compile command:

gradlew.bat assemble

(the gradle environment variable needs to be configured. Compiling is easy to time out. You can succeed by trying several times. I tried three times.)

3. After compiling, the compressed package (dex-tools-2.1) will be generated under dex2jar-2. X/DEX tools/build/distributions- SNAPSHOT.tar ，dex-tools-2.1- SNAPSHOT.zip ）, decompress a compressed package and recompile APK.

Attached is my own dex2jar:

dex-tools-2.1- SNAPSHOT.tar
