android - Robolectric & Gradle : error: cannot access BufferedImage class file for java. 找不到 awt.image.BufferedImage

Question

我对堆栈溢出进行了相当深入的研究，但到目前为止我还没有找到解决方案。

我在运行 Robolectric 测试时遇到了来自 Android Studio 的错误。

我的项目看起来是这样的:

project
 -app
     -src
      -main
      -test
   -build.gradle
 -library
     -src
       -main
       -test
   -build.gradle
build.gradle

项目的build.gradle:

buildscript {
 repositories {
    mavenCentral()
    maven { url '*********************' }
    maven { url '*********************' }
 }
 dependencies {
    classpath 'com.android.tools.build:gradle:0.12.+'
    classpath 'org.robolectric:robolectric-gradle-plugin:0.11.+'
 }
}

allprojects {
 repositories {
    mavenCentral()
    maven { url '*********************' }
    maven { url '*********************' }
 }
}

应用的build.gradle:

apply plugin: 'com.android.application'
apply plugin: 'robolectric'

我得到的错误:

 Error:(14, 9) Gradle: error: cannot access BufferedImage class file for java.awt.image.BufferedImage not found

输入:

./gradlew clean test --stacktrace

给我异常(exception):

我的问题当然是:如何解决它并成功运行 Robolectric 测试？任何人，请。

编辑:任何人都可以推荐使用有关正确 gradle 配置的说明的 android gradle 插件吗？
