PlayFramework 2.4和IntelliJ 14

Question

我正在嘗試將PlayFramework 2.4項目導入IntelliJ 14.1.3。 我無法導入現有的（在2.4之前的版本中創建的），因此請執行以下步驟：

1. 通過激活器創建了一個新的play-java項目： activator new appName
2. 試圖通過IntelliJ打開創建的項目。 （打開“打開”對話框，然后使用我的應用程序選擇文件夾，然后將JDK設置為1.8.0_45）

我收到此異常：

Answer 1

解決方案是刪除用戶主文件夾中的所有.sbt，.ivy，.m2文件夾。 我也刪除了SBT_HOME系統變量。 之后，IntelliJ能夠創建有效的項目。

Answer 2

在Windows上，只需刪除以下文件夾：C：\\ Users \\ .sbt在啟動intellij之前檢查系統上的sbt命令是否正常
