堆栈跟踪看起来像：

bug report有一些活动，但还没有解决方案。

Android Studio 0.5.2 ，gradle版 1.11 / 0.9.2 。

想法？

2 个答案:

答案 0 :(得分：50)

根据错误报告中的最新信息，问题是版本0.9.2是从Maven中心提供的，即使所有必要的组件都不可用（并且gradle没有将其注册为问题）。这会破坏因为缺少碎片。版本0.9.2 现在完全可用且有效，但如果您发现此错误，则您的gradle缓存已损坏。

修复：

gradle --refresh-dependencies

或删除

~/.gradle/caches

然后重新同步。

先前修复，请参阅上面的更新。

根据the bug report中的评论，version 0.9.2似乎是此问题的根源。

要修复，将gradle版本与已知良好版本0.9.1 挂钩，而不是0.9.+，0.+，+等。< / p>

在build.gradle文件中，更改

classpath 'com.android.tools.build:gradle:0.9.+'

到

classpath 'com.android.tools.build:gradle:0.9.1'

答案 1 :(得分：1)

要使用最新的Gradle版本0.9。+，您还必须更新gradlewrapper.properties文件。

打开位于gradlewrapper.properties路径下的youProjectPath/gradle/wrapper/gradlewrapper.properties文件：

从

更改distributionUrl网址 
distributionUrl=http\://services.gradle.org/distributions/gradle-1.10-all.zip

要

distributionUrl=http\://services.gradle.org/distributions/gradle-1.11-all.zip

之后，我将build.gradle依赖项更改为

classpath 'com.android.tools.build:gradle:0.9.+'

并且同步gradle文件和所有内容。

干杯
