我有一个使用 Scala 运行 play 2.5 的项目，直到今晚都运行良好。我突然不能拉一堆依赖..我不知道该怎么办..这是堆栈跟踪：

我该如何解决这个问题？

非常感谢。

【问题讨论】：

项目在 Play 2.5.18 和 scala 2.11.11

标签： scala playframework sbt

【解决方案1】：

我在 maven central 找到了这个版本：https://search.maven.org/#artifactdetails%7Cio.netty%7Cnetty-codec%7C4.0.36.Final%7Cjar

您是否明确导入依赖项？还是递归依赖？

【讨论】：

是递归依赖。可能是从游戏中拉出来的

【解决方案2】：

如果您突然找不到任何依赖项，那么您很可能遇到了暂时的网络问题，阻止您进行下载。

建议：

稍后再试。
尝试直接在浏览器中下载依赖项，看看它们是否有效。

【讨论】：

问题是，每当我在另一台笔记本电脑上克隆我的项目时，它都能完美运行......
尝试清理或重命名您的~/.ivy2 文件夹。还可以尝试手动删除项目中的所有 target 文件夹。要验证网络问题，请验证手动下载在两台笔记本电脑上的工作方式是否相同。
