gradle3.0中使用Butterknife

在gradle3.0中使用butternife目前butterknife-gradle-plugin需要降级，但是依赖库的版本可以保持不变：

build.gradle:

buildscript {
    repositories {
        jcenter()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'com.jakewharton:butterknife-gradle-plugin:8.4.0'
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
    }
}

app/build.gradle:

apply plugin: 'com.android.application'
apply plugin: 'com.jakewharton.butterknife'

dependencies {
    api ("com.jakewharton:butterknife:8.8.1") {
        //exclude group: 'com.android.support', module: 'recyclerview-v7'
        //exclude group: 'com.android.support', module: 'support-compat'
    }
    annotationProcessor "com.jakewharton:butterknife-compiler:8.8.1"
}
