使用的AndroidStudio版本为3.6

遇到一个报错：

Duplicate jar entry [android/support/design/widget/CoordinatorLayout$1.class

build.gradle文件如下: 

    compileSdkVersion 27
    buildToolsVersion "27.0.3"
    defaultConfig {
        applicationId "APP包名"
        minSdkVersion 18
        targetSdkVersion 27
        
        ....省略其它......
        .
        .
        .
dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation 'com.android.support:appcompat-v7:27.1.0'
    implementation 'com.android.support:support-v4:27.1.0'
    implementation 'com.android.support:recyclerview-v7:27.1.0'
        .
        .
        .

然后运行报错： 

然后发现在dependencies 中 加入 implementation 'com.android.support:design:27.1.1'

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation 'com.android.support:appcompat-v7:27.1.0'
    implementation 'com.android.support:support-v4:27.1.0'
    implementation 'com.android.support:recyclerview-v7:27.1.0'
    implementation 'com.android.support:design:27.1.1'

 不会报错了。
