Android Studio运行时报错：Could not resolve all dependencies for configuration ':app:_

[幻欢子]

第一次用Android Studio开发。但在Android Studio运行时报错：
Could not resolve all dependencies for configuration ':app:_debugCompile'.
Could not find any version that matches com.android.support:appcompat-v7:15.+.

但我的SDK Manager安装了该有的组件了啊，求大神帮我看看问题出现在哪里了？


再附上build.gradle文件内容：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 15
    buildToolsVersion "24.0.0"

    defaultConfig {
        applicationId "com.test.helloworld"
        minSdkVersion 14
        targetSdkVersion 15
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:15.+'
}

换个版本的v7包试试

gradle不怎么会用，我猜可以这么改compile 'com.android.support:appcompat-v7:24.0.0'
