Circular dependency between the following tasks while using firebase Crashlytics

Question

Today I just migrated from fabric crashlytics to Firebase crashlytics.

Everything is working fine with minifyEnabled false, but when I changed the minifyEnabled true I got this exception:

Circular dependency between the following tasks:
:app:checkManifestChangesDebug
\--- :app:instantRunMainApkResourcesDebug
 \--- :app:transformClassesAndDexWithShrinkResForDebug
      \--- :app:transformDexArchiveWithDexMergerForDebug
           +--- :app:preColdswapDebug
           |    \--- :app:incrementalDebugTasks
           |         +--- :app:transformClassesAndClassesEnhancedWithInstantReloadDexForDebug
           |         |    \--- :app:transformClassesWithInstantRunForDebug
           |         |         \--- :app:checkManifestChangesDebug (*)
           |         \--- :app:transformClassesWithInstantRunForDebug (*)
           \--- :app:transformClassesWithDexBuilderForDebug
                +--- :app:preColdswapDebug (*)
                \--- :app:transformClassesWithInstantRunForDebug (*)

And proguard for the crashlytics is

#PROGUARD RULE FOR FIREBASE CRASHLYTICS
#----------------------------------------------------------------------
# https://firebase.google.com/docs/crashlytics/get-deobfuscated-reports
-keepattributes *Annotation*
-keepattributes SourceFile,LineNumberTable
-keep public class * extends java.lang.Exception

# To let Crashlytics automatically upload the ProGuard or DexGuard mapping 
file, remove this line from the config file
# -printmapping mapping.txt

-keep class com.crashlytics.** { *; }
-dontwarn com.crashlytics.**
