Unable to find method 'com.android.build.gradle.api.BaseVariant.getOutputs()Ljava/util/List;

Android Studio 3.0
原因 butterknife 配置问题：

解决办法：

删除

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.2.0'
        //classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        //classpath 'com.jakewharton:butterknife-gradle-plugin:8.6.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

和 App build.gradle

apply plugin: 'com.android.application'
apply plugin: 'org.greenrobot.greendao'
//apply plugin: 'com.jakewharton.butterknife'

然后重新构建一次
