添加谷歌云模块时任务'：app：dexDebug'执行失败

Question

克隆项目https://github.com/googlesamples/google-services/tree/master/android/gcm，一切正常。

当我尝试使用向导添加模块“App Engine Backend with Google Cloud Messaging”时，我收到以下错误：

Error:Execution failed for task ':app:transformClassesWithDexForDebug'. > com.android.build.transform.api.TransformException: java.lang.RuntimeException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_79\bin\java.exe'' finished with non-zero exit value 1

现在我尝试在我的 build.gradle defaultConfig 中添加它

multiDexEnabled true 

并清理项目并重新编译。但我总是得到同样的错误。最后我尝试从项目中删除表单（想恢复正常功能）但我收到以下错误：

    Installing gcm.play.android.samples.com.gcmquickstart
DEVICE SHELL COMMAND: pm install -r "/data/local/tmp/gcm.play.android.samples.com.gcmquickstart"
    pkg: /data/local/tmp/gcm.play.android.samples.com.gcmquickstart

DEVICE SHELL COMMAND: pm uninstall gcm.play.android.samples.com.gcmquickstart
DELETE_FAILED_INTERNAL_ERROR

有人可以帮我吗？你会采取与我的情况相同的步骤吗？提前谢谢你

已解决

大家好，我自己找到了答案。我希望它可以对有同样问题的人有所帮助。 当 Android Studio 生成后端模块时，在 build.gradle(Module:app) 的依赖项末尾添加这一行

compile project(path: ':backend', configuration: 'android-endpoints')

你有这样的东西：

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'

compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.1.0'
compile 'com.android.support:recyclerview-v7:23.0.1'
compile 'com.android.support:palette-v7:23.0.1'
compile 'com.android.support:cardview-v7:23.0.1'
compile 'com.android.support:support-v4:23.0.1'
compile 'com.google.android.gms:play-services-gcm:8.1.0'
compile project(path: ':backend', configuration: 'android-endpoints')

}

解决方法是将自动生成的行移到依赖声明的顶部，如下所示：

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile project(path: ':backend', configuration: 'android-endpoints')
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.1.0'
compile 'com.android.support:recyclerview-v7:23.0.1'
compile 'com.android.support:palette-v7:23.0.1'
compile 'com.android.support:cardview-v7:23.0.1'  
compile 'com.android.support:support-v4:23.0.1'  
compile 'com.google.android.gms:play-services-gcm:8.1.0'

}

更新

如果不解决试试：

Build->Make Project
Build->Make Module 'app'
Build->Clean Project
Build->Rebuild Project
