无法从最终类inheritance

我在Windows 7 x64上安装了Android studio 0.4.2。 尝试从工作室创建简单的项目，但我收到一个错误：

Cannot inherit from final class 

• 我试试了studio64.exe和studio.exe。
• 我尝试了jdk 1.7 u45 x86和jdk 1.7 u51 x64
• 来自回购的gradle 1.9。

在我的虚拟机XPx32中，所有这些文件a-studio工作得很好（我只是将android-studio，c：\ Users \％user％。AnroidStudioPreview，c：\ Users \％user％.gradle从我真正的vachine复制到虚拟中） 。

我在ntlm的代理服务器后面。

日志是：

更新

在我的项目3个子项目中。 顶级build.gradle

 // Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.7.+' } } allprojects { repositories { mavenCentral() } } 

主项目build.gradle

 apply plugin: 'android' android { compileSdkVersion 18 buildToolsVersion "19.0.1" defaultConfig { minSdkVersion 15 targetSdkVersion 18 } buildTypes { release { runProguard false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt' } } } dependencies { compile project(':wheel') compile project(':appRater') compile files('libs/android-support-v13.jar') compile files('libs/libGoogleAnalyticsServices.jar') } 

在所有子项目中，build.gradle是：

 apply plugin: 'android-library' android { compileSdkVersion 18 buildToolsVersion "19.0.1" defaultConfig { minSdkVersion 15 targetSdkVersion 18 } release { runProguard false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt' } } 

Answer 1

这似乎是Android工作室中的一个错误，不是具体但与之相关

 Cannot inherit from final Class

关闭Android Studio，进行备份并从工作室安装目录中删除所有这些文件并重新启动它，可能会对您有所帮助

 android-studio/plugins/android/lib/builder-0.6.1.jar android-studio/plugins/android/lib/builder-model-0.6.1.jar android-studio/plugins/gradle/lib/gradle-base-services-1.8.jar android-studio/plugins/gradle/lib/gradle-build-setup-1.8.jar android-studio/plugins/gradle/lib/gradle-core-1.8.jar android-studio/plugins/gradle/lib/gradle-messaging-1.8.jar android-studio/plugins/gradle/lib/gradle-native-1.8.jar android-studio/plugins/gradle/lib/gradle-plugins-1.8.jar android-studio/plugins/gradle/lib/gradle-tooling-api-1.8.jar android-studio/plugins/gradle/lib/gradle-wrapper-1.8.jar android-studio/plugins/gradle/lib/guava-11.0.2.jar 

Answer 2

除了上面的答案和删除文件之前，我打开了破坏的项目，Android Studio告诉我gradle已经过时了，并且消息中有一个小的URL说明了修复gradle …这样做了，但是没有完全解决我的问题。 之后，我删除了上面的文件，一切正常。
