我已经启动了一个具有Intellij Idea的新Android项目，并遇到了此错误。我只在gradle-wrapper.properties中将Gradle版本更改为5.2.1。为什么Intellij创建一个不起作用的项目？我还尝试将这个Android项目添加到现有项目中，并带有Gradle KTS脚本，并且我遇到了相同的错误。

这是一个已知问题。作为解决方法，使用Intellij Idea与Jetbrains Runtime 8而不是11（仍然是实验性的）。
只需安装JetBrains工具箱，然后单击" Intern Intellij Idea Community/Ultimate"，而无需" JBR11"在Manjaro Linux上为我工作。现在，我的Android项目的Gradle构建。
