PlayFramework 2.4 和 IntelliJ 14

Question

我正在尝试将 PlayFramework 2.4 项目导入 IntelliJ 14.1.3。我无法导入现有的（在 2.4 之前创建的），所以做了这些步骤：

1. 通过激活器创建了一个新的 play-java 项目：activator new appName
2. 试图通过 IntelliJ 打开创建的项目。 （打开“打开”对话框，然后选择包含我的应用程序的文件夹，然后将 JDK 设置为 1.8.0_45）

我遇到了这个异常：

Answer 1

解决方案是删除用户主文件夹中的所有 .sbt、.ivy、.m2 文件夹。我还删除了 SBT_HOME 系统变量。之后，IntelliJ 能够创建有效的项目。

Answer 2

在 windows 上只需删除文件夹：C:\Users\.sbt 在启动 intellij 之前检查系统上的 sbt 命令是否正常
