未找到Gradle DSL方法：將模塊導入到項目後的'compileSdkVersion（）'

Question

我在Android Studio中有一個項目。我需要在這個項目中導入一個模塊：https://github.com/square/android-times-square/ 這個包裏有一個庫和一個樣本。我導入他們兩個。 我下載.ZIP和Android Studio中做文件 - >新建 - >導入模塊 而在此之後，我得到了graddle錯誤：

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 

我點擊了此錯誤消息中列出的所有鏈接。但它沒有幫助。 Gradle腳本有什麼問題？ 我不明白爲什麼有這麼多的文件的gradle和我需要修復（（（

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 
    targetSdkVersion 25 
} 

allprojects { 
    repositories { 
     jcenter() 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 

的build.gradle（庫哪一個）

apply plugin: 'com.android.library' 
apply plugin: 'checkstyle' 

task checkstyle(type: Checkstyle) { 
    configFile rootProject.file('checkstyle.xml') 
    source 'src/main/java' 
    ignoreFailures false 
    showViolations true 
    include '**/*.java' 

    classpath = files() 
} 

afterEvaluate { 
    if (project.tasks.findByName('check')) { 
    check.dependsOn('checkstyle') 
    } 
} 

android { 
    compileSdkVersion rootProject.ext.compileSdkVersion

    defaultConfig { 
    minSdkVersion rootProject.ext.minSdkVersion

    lintOptions { 
    warning 'MissingTranslation' 
    textReport true 
    textOutput 'stdout' 
    } 
} 

dependencies { 
    testCompile deps.festandroid 
    testCompile deps.junit 
    testCompile deps.robolectric 
    testCompile deps.intellijannotations 
} 

apply from: rootProject.file('gradle/gradle-mvn-push.gradle') 

的build.gradle（樣品）

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion rootProject.ext.compileSdkVersion 
    buildToolsVersion rootProject.ext.buildToolsVersion 

    compileOptions { 
    sourceCompatibility rootProject.ext.sourceCompatibilityVersion 
    targetCompatibility rootProject.ext.targetCompatibilityVersion 
    } 

    defaultConfig { 
    applicationId 'com.squareup.timessquare.sample' 
    minSdkVersion rootProject.ext.minSdkVersion 
    targetSdkVersion rootProject.ext.targetSdkVersion 
    versionCode 1 
    versionName '1.0.0' 
    } 

    lintOptions { 
    disable 'MissingTranslation' 
    } 
} 

dependencies { 
    compile project(':library') 
} 

的build.gradle（模塊：APP）

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 25 
    buildToolsVersion "25.0.2" 
    defaultConfig { 
     applicationId "com.myproject.myproject2"

      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 
     exclude group: 'com.android.support', module: 'support-annotations' 
    })

    compile 'com.android.support:support-v4:25.3.1' 
    testCompile 'junit:junit:4.12' 
} 

settings.gradle

include ':app', ':sample', ':library'

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

你不能在頂層文件使用此語法：

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

相反，您可以使用此語法（請注意=）

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