我已经更改了

classpath("com.android.tools.build:gradle:3.4.1") to 3.4.2

没用。我不明白这个问题。需要支持。我已经重新安装了模块,但它给出了同样的问题。

下面是我的路径变量...

System variables

By Changing The SDK version, I have fixed my issue... and some other have suggested the same thing.

我的 jdk1.8.0_20 不工作。所以我刚刚将 jdk 更改为 jdk-12.0.2。不知道对不对

这个问题与其他一些问题有关,但我当时找不到...

Problem was in minor JDK version. Scala 2.12 require's newer version of JDK then 1.8.0_111. So after JDK upgrade everything work.

我希望它能帮到一些人。

谢谢。
