android - CI 环境中的 Robolectric

Question

我遇到了一个问题，我的 robolectric 测试通过了我的终端:./gradlew 测试和相同的命令，使用 circleci 上的所有工具正确配置给我这个错误:

我正在使用 robolectric 3.0-rc3，我相信这个错误来自 robolectric 本身，但我不知道从哪里寻找解决这个错误的任何线索。

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();
