Robolectric 在 CI 环境中

Question

我运行遇到一个问题，我的 robolectric 测试通过了我的终端： ./gradlew test 同样的命令，正确配置了 circleci 上的所有工具，给我这个错误：

我正在使用 robolectric 3.0-rc3，我相信这个错误来自 robolectric 本身，但我不知道在哪里寻找解决这个错误的线索。

解决方案是向 ImageLoader 添加内存缓存，如下所示：

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(this)
                .memoryCache(new WeakMemoryCache())
                .build();
