所以我用它来安装一个示例Flink项目。 https://github.com/tillrohrmann/flink-project.g8
我正在尝试使用这个模板，让我开始编写一个Flink摄取应用程序，而不必担心依赖，但它会适得其反。事实证明，当我尝试与sbt同步时，我无法找到Flink（不会说谎，但这部分对我来说甚至模糊）。想知道是否有人知道如何让我的项目找到Flink。很高兴使用这项技术。

编辑：我得到了要构建的项目，但我无法在IDE中单击。我的意思是当我尝试进入Flink类时，它无法找到声明。
答案 0 :(得分：3)
Flink Scala currently only supports Scala 2.10 and 2.11，因此您必须将Scala降级为其中一个版本或使用其Java接口。
