运行测试时出现“错误：Gradle：prolog中不允许内容”(“Error:Gradle: Content is not allowed in prolog” when running tests)

运行测试时出现“错误：Gradle：prolog中不允许内容”(“Error:Gradle: Content is not allowed in prolog” when running tests)

使用Android Studio，当我尝试运行所有单元测试时，它几乎立即失败，并在Messages（Gradle Build）中出现以下错误：

Error:Gradle: Content is not allowed in prolog. Error:Gradle: Execution failed for task ':Module:mergeDebugAndroidTestResources'. > /Users/me/path/to/my/project/src/test/resources/fixtures/activity_feed.json:0:0: Error: Content is not allowed in prolog.

似乎内容的另一个变体不允许在prolog错误中，这通常没有意义，因为我发现了搜索解决方案。 在我的例子中，它指向一个JSON文件，显然不包含任何prolog代码。

Using Android Studio, when I try to run all my Unit Tests, it fails almost immediately with following error in Messages (Gradle Build):

Error:Gradle: Content is not allowed in prolog. Error:Gradle: Execution failed for task ':Module:mergeDebugAndroidTestResources'. > /Users/me/path/to/my/project/src/test/resources/fixtures/activity_feed.json:0:0: Error: Content is not allowed in prolog.

Seems like yet another variant of Content is not allowed in prolog error, which doesn't often makes sense, as I found out searching for a solution. In my case, it points to a JSON file, which obviously doesn't contain any prolog code.

最满意答案

查找构建变体视图：

左侧工具窗格 查看 - >工具窗口 - >构建变体

在那里，找到：

测试工件： Android Instrumentation测试

而是Android Instrumentation Tests选择：

测试工件： 单元测试

Find Build Variants view:

left tool pane View -> Tool Windows -> Build Variants

Once there, locate:

Test Artifact: Android Instrumentation Tests

and instead Android Instrumentation Tests select:

Test Artifact: Unit Tests
