java.io.IOException: Invalid keystore format

执行apk签名命令格式如下: C:/Users/root/AppData/Local/Android/Sdk/build-tools/30.0.3/apksigner sign --ks C:\development\xxxxx.jks --ks-key-alias xxxx --ks-pass pass:xxxx --key-pass pass:xxx --out C:\development\xxxxx_signed.apk C:\development\xxorigin_app.apk

• 详细报错如下:

这个报错究其原因是签名的jks文件和运行的apksigner命令版本不匹配导致,姑且猜测是一个apksigner执行文件对应一个时段的jks生成器,因此要解决这个问题,需要确定AndroidSdk里面一个合适的build-tools版本,具体到你AndroidSdk的build-tools查看有哪些版本,然后用这些版本尝试替换掉命令中的详细版本(如:C:/Users/root/AppData/Local/Android/Sdk/build-tools/替换的具体版本/apksigner),能执行成功为准!
