在使用 Android Studio 3.3 及更高版本的 java-kotlin 混合中，我收到 invalid type code: 68 错误消息。使用 gradle 5.1 及更高版本时，我收到一条附加消息“由于包含 Kotlin 模块，不支持新的 Gradle 同步”

如何在android studio 3.3中重现:

1) 在java中创建一个空白activity的新android项目

2) 创建一个 kotlin 类文件

3) 点击configure kotlin按钮，将kotlin插件和库添加到项目中

4) 同步分级

我的项目过去在之前的 Android Studio 稳定版本 (3.2.1) 上运行良好

最佳答案

更改首选项 > 实验性 > 仅同步 Activity 变体(取消选中此项)。

或者，在项目文件中手动编辑相应设置:尝试在 .idea/workspace.xml 中将 not.eligible.for.single.variant.sync 设置为 true

您可以如下所示直接编辑 XML 或使用 IntelliJ 的设置 UI:

  <component name="PropertiesComponent">
    <property name="not.eligible.for.single.variant.sync" value="true" />
  </component>

这是因为 Kotlin 不支持单一变体同步

Note: This optimization fully supports projects that include Java and C++ languages, and has some support for Kotlin. When enabling the optimization for projects with Kotlin content, Gradle sync falls back to using full variants internally.

https://developer.android.com/studio/build/optimize-your-build#single_variant_sync

至于为什么 Gradle 无法自动回退到完整的变体同步，或者为什么 Android Studio 没有自动为您设置此标志，我不知道。

关于安卓工作室 3.3 : New Gradle Sync is not supported due to containing Kotlin modules (invalid type code: 68)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/54201216/
