Android从Gradle和Kotlin的各种错误

Gradle和Kotlin是怎么回事? 我还没有开始编码,并已经后悔回到Android 🙁

Gradle项目

buildscript { ext.kotlin_version = '1.1.3-2' repositories { jcenter() mavenCentral() maven { url 'https://maven.google.com' } } dependencies { classpath 'com.android.tools.build:gradle:2.3.3' classpath 'com.google.gms:google-services:3.1.0' classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version" } } allprojects { repositories { jcenter() maven { url 'https://maven.google.com' } mavenCentral() } } task clean(type: Delete) { delete rootProject.buildDir } 

Gradle模块

看起来你错过了Kotlin标准库作为编译依赖。
