我将从GitHub下载的项目作为模块导入到我的Android Studio项目中."导入模块..."向导工作正常,但当Adroid Studio尝试重建项目时,它返回给我这个错误:

Cannot get property 'compileSdkVersion' on extra properties extension as it does not exist Open File

该错误与导入模块的"build.gradle"文件中的此行相关:

compileSdkVersion rootProject.compileSdkVersion

我试图在项目"build.gradle"中添加"ext"部分,如下所示:

ext {
    compileSdkVersion 26
}

但是这样我收到一个新的错误:

Gradle DSL method not found: 'compileSdkVersion()' Possible causes: ... 

I followed the steps in the Flutter document and tried to build my first Flutter app in Intellij IDEA. And when I try to run it,there was an error about my JAVA_HOME variable. And an error about cannot resolve symbol "Properties" in the build.gradle file. I really don't know what to do.

This is my error information displayed in the Console window.
