R2 not found in my library module

[Jafar396]

I try to merge two project and when I convert the second project to library module the @BindView(R.id.xxx) in library is tell me (attribute value must be a constant) and when I research I add in my library module:
apply plugin: 'com.android.library'
apply plugin: 'com.jakewharton.butterknife'
and:
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
and:
implementation 'com.jakewharton:butterknife:10.2.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:10.2.1'
and I add in my project:
dependencies {
classpath 'com.android.tools.build:gradle:3.6.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.jakewharton:butterknife-gradle-plugin:10.2.1'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

my gradle is 5.6.4
but when I replace R to R2 , The R2 is not found
please help me

[JakeWharton]

Please provide a sample project that demonstrates the issue.

I need to help my friend
@JakeWharton

[JakeWharton]

A bunch of snippets doesn't help me reproduce your problem. I need a self-contained project zip that I can just open, hit run, and see the failure, ideally with as little other code as possible.
