我无法编译我的Android Kotlin项目。

我不知道这是什么…

Gradle日志：

错误：以下类的超类型无法解析。 请确保您在类路径中具有所需的依赖项：class android.support.v7.app.AppCompatActivity，未解析的超类型：SupportParentable

我通过改变插件调用的顺序来修复它！

的build.gradle

 buildscript { ext.android_plugin_version = '2.3.3' ext.kotlin_version = '1.1.3-2' repositories { jcenter() mavenCentral() maven { url "https://maven.google.com" } maven { url 'https://maven.fabric.io/public' } maven { url "https://jitpack.io" } } dependencies { classpath "com.android.tools.build:gradle:$android_plugin_version" classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version" classpath 'io.fabric.tools:gradle:1.+' } } allprojects { repositories { jcenter() mavenCentral() maven { url "https://maven.google.com" } maven { url 'https://maven.fabric.io/public' } maven { url "https://jitpack.io" } } } task clean(type: Delete) { delete rootProject.buildDir }
