大家好，在将 Android Studio 更新到 3.1 Canary 3 之后，我刚刚创建了新项目，但由于 gradle 同步失败:

Error:com.android.tools.idea.gradle.project.model.AndroidModuleModel.getMainArtifact()Lcom/android/tools/idea/gradle/project/model/ide/android/IdeAndroidArtifact;com.android.tools.idea.gradle.project.model.AndroidModuleModel.getMainArtifact()Lcom/android/tools/idea/gradle/project/model/ide/android/IdeAndroidArtifact;

我的 gradle 文件是:

> buildscript {
>     ext.kotlin_version = '1.2.0-rc-39'
>     repositories {
>         google()
>         jcenter()
>         maven { url "https://dl.bintray.com/kotlin/kotlin-dev"}
>     }
>     dependencies {
>         classpath 'com.android.tools.build:gradle:3.1.0-alpha03'
>         classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
>         classpath 'com.google.gms:google-services:3.1.0'
>     } }
> 
> allprojects {
>     repositories {
>         google()
>         jcenter()
>         maven { url "https://dl.bintray.com/kotlin/kotlin-dev"}
>     } }
> 
> task clean(type: Delete) {
>     delete rootProject.buildDir }
> 

还有第二个 build.gradle

最佳答案

同样的问题。卸载 Kotlin 插件(Preferences > Plugins > Kotlin > Uninstall)并使用 IDE 附带的版本解决了我的问题。
