Debug buildtype works fine, but production (with proguard and minification) throw an Exception
Caused by com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "timestamp" (class com.two_two.checkreaction.models.firebase.FireComplexResult), not marked as ignorable (0 known properties: ])

Proguard section for Firebase is the following
# Basic ProGuard rules for Firebase Android SDK 2.0.0+
-keep class com.firebase.** { *; }
-keep class org.apache.** { *; }
-keep class com.two_two.checkreaction.models.firebase.FireComplexResult
-keepnames class com.fasterxml.jackson.** { *; }
-keepnames class javax.servlet.** { *; }
-keepnames class org.ietf.jgss.** { *; }
-dontwarn org.apache.**
-dontwarn org.w3c.dom.**
# Firebase-UI
#-keepnames class com.firebase.ui.** { *; }
#-keep class com.firebase.ui.** { *; }
-dontwarn com.firebase.ui.**
Update:
-keep class com.two_two.checkreaction.models.firebase.** { *; }
solves the problem. But I don't want to keep package, I want to keep just one class.
I had a similar exception thrown in my application that uses Firebase. Solved it by moving my POJOs into a package and exclude that package from being obfuscated with this proguard rule
-keepnames class com.my.package.beans.** { *; }
