错误:执行任务':app:javaPreCompileDebug'失败。 > java.io.IOException:无法删除annotationProcessors.json

我正在尝试在Android Studio 3.0 Canary 2中的Kotlin中进行编码。当我在代码中进行更改时,我必须从Build – > Rebuild Project然后运行重建完整的应用程序

在对代码进行更改之后,只需点击运行按钮,就会随机显示此错误。

错误:执行任务':app:javaPreCompileDebug'失败。 java.io.IOException:无法删除C:\ Users \ williams \ AndroidStudioProjects \ Kotlin \ FirstDemo \ app \ build \ intermediates \ javaPrecompile \ debug \ annotationProcessors.json

可能是什么问题? 这似乎与构建工具或Kotlin编译器的问题,因为它适用于Java
