未找到Gradle DSL方法：将模块导入到项目后的'compileSdkVersion（）'

Question

我在Android Studio中有一个项目。我需要在这个项目中导入一个模块：https://github.com/square/android-times-square/ 这个包里有一个库和一个样本。我导入他们两个。 我下载.ZIP和Android Studio中做文件 - >新建 - >导入模块 而在此之后，我得到了graddle错误：

Error:(16, 0) Gradle DSL method not found: 'compileSdkVersion()' 
Possible causes: 
The project 'MyProject' may be using a version of the Android Gradle plug-in that does not contain the method 
(e.g. 'testCompile' was added in 1.1.0). 
Upgrade plugin to version 2.3.3 and sync project. The project 'MyProject' may be using a version of Gradle that does not contain the method. 
Open Gradle wrapper file. The build file may be missing a Gradle plugin. 
Apply Gradle plugin 

我点击了此错误消息中列出的所有链接。但它没有帮助。 Gradle脚本有什么问题？ 我不明白为什么有这么多的文件的gradle和我需要修复（（（

的build.gradle（MyProject的）

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.3.3' 

     // NOTE: Do not place your application dependencies here; they belong 
     // in the individual module build.gradle files 
    } 
} 

ext { 
    compileSdkVersion 25 
    buildToolsVersion "25.0.2" 
    minSdkVersion 16

Error:(16, 0) Gradle DSL method not found: 'compileSdkVersion()'

你不能在顶层文件使用此语法：

ext { 
    compileSdkVersion 25 
    buildToolsVersion "25.0.2" 
    minSdkVersion 16 
    targetSdkVersion 25 
} 

相反，您可以使用此语法（请注意=）

ext { 
    // The following are only a few examples of the types of properties you can define. 
    compileSdkVersion = 25 
    buildToolsVersion = "26.0.1" 
    ... 
}
