从 Android Studio“3.2 Canary 16”升级到“3.2 Beta 1”后出现数据绑定编译错误

Question

我刚刚将 Android Studio 从 3.2 Canary 16 升级到“3.2 Beta 1”。现在我的项目不再编译。我正在使用 Kotlin + 数据绑定，我认为这是问题所在。这是构建堆栈跟踪：

Gradle插件版本：3.2.0-beta01
Kotlin 版本：1.2.50 (jdk8)

我也尝试将 kapt "androidx.databinding:databinding-compiler:3.2.0-beta01" 添加到应用程序 gradle，但没有任何区别。

编辑：

降级到 Kotlin 1.2.41 没有解决问题。
经过更多测试，这个错误似乎出现在 Gradle 插件版本 3.2.0-alpha17 中。（alpha16 工作正常）

Answer 1

在另一个项目中测试后发现问题。我在项目级依赖项中没有以下行：

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

这以前从来都不是问题，但如果您使用 Kotlin 和数据绑定，那么在较新的 Android Studio 版本中似乎需要这样做。
