所以我有这个特定的警告，我使用了脱糖并且这个警告出现了。我的第三方依赖项之一使用它Bifunction，但由于找不到它，应用程序崩溃。我发现可能脱糖没有Bifunction类，所以jackson不能转换它。我必须说它只会在 Android-API 23 marshmallow 上出错，并且在 Android-API >23 设备上运行良好。

编辑如果我将 desugaring 设置为 true 或 false，则会发生此问题，因此我确定Bifunction从java.util.function.

代码：

List<Message> list;
list = mapper.convertValue(mapList, new TypeReference<List<Message>>() {});

当我尝试在启用 Desugaring 的情况下构建应用程序时出现警告：

Warning in C:\Users\Keivan Shirkoubian\.gradle\caches\modules-2\files-2.1\com.android.tools\desugar_jdk_libs\1.0.9\359e5e4f4784f23beb30ba454b41f6f992e58481\desugar_jdk_libs-1.0.9.jar:java/util/concurrent/ConcurrentHashMap.class:

这是崩溃日志，当我尝试将我的 mapList 映射到另一个列表 (List) 时出现。

java.util.function 包中的BiFunction要求您的项目模块与 Java 8 兼容。

尝试将您的 Gradle 插件升级到版本 3.0.0（或更高版本）并添加 Java 8 语言功能支持。检查文档链接：

如果您已经这样做了，请分享您的 Gradle 配置文件。
