Android Studio 如何在android库中集成Butterknife？

我正在处理Android中的现有项目，我想将Android项目转换为Android库。在该项目中，butterknife库用于绑定UI组件。当我尝试使用引用将项目转换为库时，项目成功同步，但使用butterknife的所有文件，我收到以下错误“属性值必须为常量”，适用于所有@BindView组件。
下面是我对Gradle文件所做的更改。

1.项目等级：
//顶层构建文件，您可以在其中添加所有子项目/模块通用的配置选项。

buildscript {
        ext.kotlin_version = '1.3.50'
    
    
        repositories {
            mavenCentral()
            google()
            jcenter()
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:3.5.3'
            classpath 'com.google.gms:google-services:4.3.3'
    
            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
            classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    
            // Add the Crashlytics Gradle plugin.
    //        classpath 'com.google.firebase:firebase-crashlytics-gradle:2.0.0-beta02'
    
            classpath 'com.jakewharton:butterknife-gradle-plugin:10.2.3'
    
        }
    }
    
    allprojects {
        repositories {
            google()
            jcenter()
            flatDir {
                dirs 'libs'
            }
        }
    }
    
    ext {
        rxJava = '2.2.0'
        rxAndroid = '2.1.0'
    }
    
    task clean(type: Delete) {
        delete rootProject.buildDir
    }

我也引用了butterknife doc并进行了相应的更改。但是我无法解决R2的错误。

@BindView(R2.id.user) EditText userName;

我怎样才能做到这一点？
任何帮助都将不胜感激。
