无法同步 Gradle,找不到 com.android.support:support-annotations:23.3.0

Failed to Sync Gradle, could not find com.android.support:support-annotations:23.3.0

安装 Butter Knife 依赖项会产生此错误

Error:Could not find com.android.support:support-annotations:23.3.0.
Required by:
    Butter:app:unspecified
    Butter:app:unspecified > com.jakewharton:butterknife:8.0.1
    Butter:app:unspecified > com.jakewharton:butterknife-compiler:8.0.1 > com.jakewharton:butterknife-annotations:8.0.1

Please install the Android Support Repository from the Android SDK Manager.

我已经安装了支持库,但仍然出现此错误。这是 Gradle 依赖项的样子

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.1'
    compile 'com.android.support:support-annotations:23.3.0'
    compile 'com.jakewharton:butterknife:8.0.1'
    apt 'com.jakewharton:butterknife-compiler:8.0.1'

}

我还添加了插件 apply plugin: 'com.neenbedankt.android-apt' 和存储库

jcenter()
        mavenCentral()
        maven{
            url 'https://oss.sonatype.org/content/repositories/snapshots/'
        }

在 SDK 管理器中更新您的 Google 存储库

将以下内容添加到您的 build.gradle 文件中:

configurations.all {
    resolutionStrategy {
        force 'com.android.support:support-annotations:23.3.0'
    }
}

更新Android 支持存储库。

一种解决方案是在 build.gradle(模块:app)中用 "compileOnly" 替换 "provided"。
