未能在Android中同步螢火石的gradle在Android

Question

我想在我的項目中使用firebase sdk，在這個項目中我無法同步gradle.I已將jdk從1.7更新爲1.8以及更新了谷歌存儲庫， Android SDK和工具latestt版本，但即使我得到錯誤，因爲無法加載類'com.google.gson.JsonObject'。

項目搖籃：

buildscript { 
repositories { 
    jcenter() 
} 
dependencies { 
    classpath 'com.android.tools.build:gradle:1.0.0' 
    classpath 'com.google.gms:google-services:3.0.0' 
    // NOTE: Do not place your application dependencies here; they belong 
    // in the individual module build.gradle files 
} 
} allprojects { 
repositories { 
    jcenter() 
} 
} 

模塊搖籃：

apply plugin: 'com.android.application' 

機器人{ 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' 
    } 

} 
packagingOptions{ 
    exclude 'META-INF/LICENSE' 
    exclude 'META-INF/LICENSE-FIREBASE.txt' 
    exclude 'META-INF/NOTICE' 

} 
}dependencies { 
compile fileTree(dir: 'libs', include: ['*.jar']) 
compile 'com.android.support:appcompat-v7:23.1.1' 
compile 'com.firebase:firebase-client-android:2.4.0' 
compile 'com.google.firebase:firebase-storage:9.2.1' 
compile 'pub.devrel:easypermissions:0.1.9' 
compile 'com.google.firebase:firebase-core:9.2.1' 
compile 'com.google.firebase:firebase-auth:9.2.1' 
} 
apply plugin: 'com.google.gms.google-services' 

錯誤：

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.

您發佈的錯誤信息中有提到的解決方案：

Possible causes for this unexpected error include:

• Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network)
• The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. Stop Gradle build processes (requires restart)

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

重新啓動IDE後也做File -> Invalidate Cache/Restart因爲它說你的緩存已損壞。從談話中評論

更新的先決條件應該得到滿足。正如你所提到的，你使用的是AS 1.0.1，它比firebase要求的要低--AS 1.5以上。升級你的Android Studio，你應該很好。
