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),所以做了以下步骤:

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,然后使用我的应用程序选择文件夹,然后将JDK设置为1.8.0_45)

我得到了这个例外:

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.我也删除了SBT_HOME系统变量.之后,IntelliJ能够创建有效的项目.
