android - 无法在 android 中同步 gradle for firebase

Question

我在 android 中使用 firebase sdk，我收到一个错误，因为无法加载类 'com.google.Gson.JsonObject'。即使我已经将 jdk 从 1.7 更改为 1.8，但它没有用。任何人知道为什么不同步了。

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.1"

defaultConfig {
    applicationId "nidhinkumar.firebaseexample"
    minSdkVersion 15
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),   'proguard-rules.pro'
    }
}   }
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:24.0.0-alpha1'
compile 'com.google.firebase:firebase-core:9.2.1'
}   apply plugin: 'com.google.gms.google-services'

错误:

Error:Unable to load class 'com.google.gson.JsonObject'.
Possible causes for this unexpected error include:<ul><li>Gradle's  dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)   <a href="syncProject">  Re-download dependencies and sync project (requires network)</a></li><li>The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.<a href="stopGradleDaemons">Stop Gradle build processes (requires restart)</a></li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

我也遇到了同样的问题，但是在更新这个存储库之后它会工作 只需将勾选标记的文件更新为最新版本即可使用
