Kotlin Android Studio 3.0 找不到方法com.android.build.gradle.internal.variant.BaseVariantData.getOutputs()LjavautilList

Trying to start a new Kotlin project with Android Studio 3.0 Canary 1 displays this error. Full trace:

错误:找不到方法

• Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network)
• The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. Stop Gradle build processes (requires restart)
• 您的项目可能正在使用

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

I've tried the first two options and the third-party plugins are left as default.

task clean(type: Delete) {
    delete rootProject.buildDir
}

我自己没有碰过这些值，它们是默认值.创建一个非Kotlin的新项目没有这个问题.
