Why I get java.lang.NoSuchFieldError: No static field xxxx of type I in class Lpl/myapp/mobile/main/BR; or its superclasses?

I have configurated databinding in android app project like below. and I get error on every field which is defined in xml file (as variable). I don't know if it's related but I use the newest android studio.

I use only debug. Yes also i try clean project. ivalidate and restart android studio. Unistall app and isntal to clean device. I also made factory reset on my Mi Box.

android {

compileSdkVersion "28.0.3"

defaultConfig {
    applicationId "pl.myapp.app"
    minSdkVersion 23
    targetSdkVersion 28
    versionCode 28
    versionName "1"
    resConfigs "en", "pl"
}

buildFeatures {
    dataBinding = true
}

buildTypes {
    release {
        minifyEnabled false
        debuggable false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }

    uat {
        applicationIdSuffix ".uat"

        debuggable true
        minifyEnabled false
    }

    debug {
        applicationIdSuffix ".dev"

        debuggable true
        minifyEnabled false
    }

}

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

lintOptions {
    disable "NotSibling"
    abortOnError false
}

}

but I get exception (and app crashes) with:

java.lang.NoSuchFieldError: No static field episode of type I in class Lpl/myapp/mobile/tv/BR; or its superclasses (declaration of 'pl.myapp.mobile.tv.BR' appears in /data/app/pl.myapp.app.atv.dev-WdbOpjR9fmv54PzXTST74w==/base.apk:classes2.dex)

Fragment of MainSectionItemCardBindingImpl class:

    public void setEpisode(@Nullable pl.myapp.mobile.tv.ui.model.MainCarouselItem Episode) {
       this.mEpisode = Episode;
       synchronized(this) {
           mDirtyFlags |= 0x1L;
       }
       notifyPropertyChanged(BR.episode); //line 88
       super.requestRebind();
   }

Fragment of SectionCardPresenter class:

override fun onBindViewHolder(viewHolder: DataBoundLeanbackViewHolder<MainSectionItemCardBinding>, item: MainCarouselItem?) {
    viewHolder.binding.episode = item //line 25
    viewHolder.binding.root.setOnClickListener { onItemClickListener?.invoke(item) }

and fragment of xml file:

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools">

    <data>

        <import type="android.view.View" />

        <variable
                name="episode"
                type="pl.myapp.mobile.tv.ui.model.MainCarouselItem"/>

    </data>

all other binding are working like access to views via binding object.
