新鲜的kotlin android项目配置错误

Hyp*_*erX 5 android kotlin android-studio android-gradle-plugin

将Android Studio更新为3.1,并创建了新的Kotlin项目,并在主应用程序中添加了新的Kotlin模块.现在尝试构建项目,它在配置构建失败时出现"发生配置项目的问题':app'."

构建树下的错误有些泛泛:

我试图使缓存无效,它将无法正常工作.该项目正常构建,但当我点击运行'app'时,这就出现了.

这是我的Gradle配置(它刚生成一个):

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
  ext.kotlin_version = '1.2.31'
  repositories {
    google()
    jcenter()
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:3.1.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
  }
}

所以这个问题是由即时运行引起的，当我禁用它时我可以正常构建它。我还向谷歌报告了错误，一旦我获得更多信息，我将更新这个答案。

编辑： 已报告错误，并已被谷歌标记为已修复。

编辑 2： 3.1.2 中修复了错误（启用即时运行时，由运行命令触发时新 Kotlin 项目的构建失败。）（https://developer.android.com/studio/releases/index.html#3 -1-0 )
