Question

我有一个项目，我正在使用intellJ。前段时间我删除了该项目;现在我想再次参与这个项目。但是，在克隆项目后，我无法将项目导入Intellj 2017.2.6。我还安装了最新的Scala插件。

这是日志：

Answer 1

执行以下步骤，看看它是否解决了您的问题：

重新启动/关闭IntellJ ：您可以毫无问题地执行sbt clean compile吗？如果是这样，那就是IntellJ问题，所以首先关闭/重启IntellJ。
删除.idea文件：首先确定将文件夹复制/粘贴到新路径。在新文件夹中删除.idea文件（Intellj使用的生成文件）。
导入项目：在intellJ中转到File > open并在新文件夹中打开项目，然后选择自动导入＆＃39;。确保您的scala和sbt版本与build.sbt相同。
使Cach无效 e：转到File > Invalidate Cache / Restarts。当我在基于Gradle的项目中工作时，这也解决了我的问题。

Answer 2

您的项目正在使用sbt 1.1，并且有一个错误阻止在IntelliJ 2017.2中导入。升级到IntelliJ / Scala 2017.3.11或更高版本应该修复它。

将现有sbt项目导入IntelliJ
