在使用Android Studio 3.3及更高版本的java-kotlin混合中，我收到了无效的类型代码：68 错误消息。当使用gradle 5.1及更高版本时，我收到一条额外的消息，提示“ 由于包含Kotlin模块，因此不支持New Gradle Sync ”
如何在android studio 3.3中重现：
1）使用空白活动在Java中创建一个新的android项目
2）创建一个kotlin类文件
3）单击配置kotlin按钮，将kotlin插件和库添加到项目中
4）同步gradle
我的项目过去在以前的Android Studio稳定版本（3.2.1）上运行良好

答案 0 :(得分：0)
尝试在.idea / workspace.xml中将not.eligible.for.single.variant.sync设置为true
<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
注意：此优化完全支持包含Java和Java的项目。 C ++语言，并且对Kotlin有一些支持。启用时 对于Kotlin内容的项目进行了优化，Gradle同步会回退 内部使用完整变体。
https://developer.android.com/studio/build/optimize-your-build#single_variant_sync
关于Gradle为什么无法自动回退到完整变体同步，或者为什么Android Studio没有为您自动设置此标志的原因，我不知道。
