在this issue中，将以下规则添加到proguard-rules.pro文件：

-keepnames class com.fasterxml.jackson.databind.** { *; }
-dontwarn com.fasterxml.jackson.databind.*
-keepattributes InnerClasses

-keep class org.bouncycastle.** { *; }
-keepnames class org.bouncycastle.* { *; }
-dontwarn org.bouncycastle.*

-keep class io.jsonwebtoken.** { *; }
-keepnames class io.jsonwebtoken.* { *; }
-keepnames interface io.jsonwebtoken.* { *; }

-dontwarn javax.xml.bind.DatatypeConverter
-dontwarn io.jsonwebtoken.impl.Base64Codec

-keepnames class com.fasterxml.jackson.** { * ; }
-keepnames interface com.fasterxml.jackson.** { *; }
