Android 错误：原因：安装插件后未指定CompileSDK版本

我试着安装这个。首先，我得到了

无法添加任务“clean”，因为具有该名称的任务已存在。

然后我用这行注释了它

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

在build.gradle中（项目：XXX）

然后我犯了个错误

原因：未指定compileSdkVersion。

即使它已经在build.gradle文件中指定了

build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    buildToolsVersion "27.0.3"
    useLibrary 'org.apache.http.legacy'
    defaultConfig {
        applicationId "www.pro_cs_is.com"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:animated-vector-drawable:27.1.1'
    implementation 'com.android.support:exifinterface:27.1.1'
    implementation 'com.android.support:design:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.1'
    implementation 'com.android.support:cardview-v7:27.1.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation ('com.android.support.test.espresso:espresso-core:3.0.2',{
    exclude group: 'com.google.code.findbugs'})
    implementation 'com.squareup.retrofit2:retrofit:2.4.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
    implementation 'com.github.bumptech.glide:glide:4.7.1'
    implementation 'org.jsoup:jsoup:1.11.3'
    implementation 'com.google.apis:google-api-services-blogger:v3-rev57-1.23.0'
    implementation 'com.squareup.picasso:picasso:2.71828'
    implementation 'com.j256.ormlite:ormlite-android:5.1'
    implementation 'com.j256.ormlite:ormlite-core:5.1'
}

• 在中应用插件
• 仅适用于build.gradle（模块：应用程序）
• 如下

  apply plugin: 'com.android.application'
  apply plugin: 'ormgap'
  
  android {
  compileSdkVersion 27
  buildToolsVersion "27.0.3"
  useLibrary 'org.apache.http.legacy'
  defaultConfig {
  applicationId "www.pro_cs_is.com"
  minSdkVersion 15
  targetSdkVersion 27
  versionCode 1
  versionName "1.0"
  testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
  }
  buildTypes {
  release {
      minifyEnabled false
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-   rules.pro'
     }
     }
     }
  
    dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:animated-vector-drawable:27.1.1'
    implementation 'com.android.support:exifinterface:27.1.1'
    implementation 'com.android.support:design:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.1'
    implementation 'com.android.support:cardview-v7:27.1.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation ('com.android.support.test.espresso:espresso-core:3.0.2',{
    exclude group: 'com.google.code.findbugs'})
    implementation 'com.squareup.retrofit2:retrofit:2.4.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
    implementation 'com.github.bumptech.glide:glide:4.7.1'
    implementation 'org.jsoup:jsoup:1.11.3'
    implementation 'com.google.apis:google-api-services-blogger:v3-rev57-1.23.0'
    implementation 'com.squareup.picasso:picasso:2.71828'
    implementation 'com.j256.ormlite:ormlite-android:5.1'
    implementation 'com.j256.ormlite:ormlite-core:5.1'
   }
  

• 并将其从build.gradle（项目：XXX）中删除

• 我希望这会有所帮助

不要在根项目的

build.gradle中应用插件。。。
