Question

很抱歉这个愚蠢的问题但是在安装Android Studio之后，在创建新项目时它给了我以下错误：

Error:Failed to resolve: com.android.support:support-core-ui:27.1.1

我在gradle依赖文件中添加了这个依赖项，如下所示：

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:appcompat-v7:27.+'
    compile "com.android.support:support-core-ui:27.1.1"
    testCompile 'junit:junit:4.12'
}

但它仍然显示相同的错误。请建议我解决这个问题的一些解决方案。

Build.gradle for My project:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.1'

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

allprojects {
    repositories {
        jcenter()
    }
}

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

您缺少存储库URL 添加以下内容：

buildscript {
    repositories {
        google()
        jcenter()
    }
    ...
}
allprojects {
    repositories {
        google()  
        jcenter()
        ...
    }
}

如果您使用的Gradle版本低于4.1，请使用以下代替google()：

maven {
    url 'https://maven.google.com'
    // An alternative URL is 'https://dl.google.com/dl/android/maven2/'

}

Android Studio无法解析：com.android.support:support-core-ui:27.1.1
