使用Android Studio（Gradle）時會丟失一些工件並且Robolectric

Question

我下載了Robolectric Samples並由Android Studio（版本1.2.1.1）導入。下android-api-19我追加依賴性等如下：

dependencies { 
testCompile "junit:junit:4.10" 
testCompile "org.json:json:20080701" 
testCompile "org.ccil.cowan.tagsoup:tagsoup:1.2" 
testCompile "org.assertj:assertj-core:1.7.0" 
testCompile "org.robolectric:robolectric:${robolectricVersion}" 
testCompile "org.robolectric:android-all:4.4_r1-robolectric-1" 
testCompile "org.robolectric:shadows-core:3.0-rc2" 

} 

我可以通過Project視圖看到json，tagsoup，shadows-core和android-all庫。我也可以在$ {GRADLE_HOME} /caches/modules-2/files-2.1目錄下看到它們。但是當我使用Gradle Test運行該項目時，會發生錯誤：

Unable to resolve artifact: Missing: 
---------- 
1) org.ccil.cowan.tagsoup:tagsoup:jar:1.2 

    Try downloading the file manually from the project website. 

    Then, install it using the command:

    Alternatively, if you host your own repository you can deploy the file there:

任何建議？

Answer 1

如果你看看錯誤消息，你可以看到它正在看的Maven倉庫。我能夠通過更新我的~/.m2目錄中的settings.xml文件來解決此問題。

Answer 2

我的問題是運行配置中的工作目錄。 它指向錯誤的目錄。

選擇運行，然後編輯配置...。使用左上角的綠色+符號添加新的運行配置並選擇Android JUnit。讓你的JUnit運行配置如下所示：

在使用模塊的類路徑中選擇您的Android應用程序的應用模塊。作爲工作目錄使用您的應用程序模塊的目錄。類是包含你的單元測試的文件（在這種情況下是你的ctivityTest類）。
