回答1:

According to the Butter Knife readme you need

buildscript {
    repositories {
        mavenCentral()
    }
   dependencies {
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}

in the build.gradle file in the root directory of your Android Studio project.

回答2:

Add

    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

in dependencies in your top-level (project) build.gradle file.

回答3:

 dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'me.tatarka:gradle-retrolambda:3.1.0'
    classpath 'org.robolectric:robolectric-gradle-plugin:1.0.1'
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
}
