Playframework 2.0 为什么activator会出现“故障”；IllegalArgumentException:需求失败“；在创建新的play项目时？

我使用的是Windows7和Java8

我正试图创建一个新的Play Framework项目，如下所示：

activator new proj play-java

我得到了下面的例外

我下载了完整的activator安装包。我更新了它，以确保所有内容都对每个文件具有权限。堆栈跟踪中的

index.db687DFD472

文件实际上是一个目录，但它一定是在命令执行期间创建的。我已经删除了

.activator

项目并重新运行了该命令，但它仍然失败，并出现了相同的错误

它已交叉发布到activator问题跟踪器。

我会用任何答案更新其他网站。

tl；dr执行

激活器“完全重新启动”

---

reboot full

背后的想法是清除所有本地sbt缓存并重新启动。似乎

~/.sbt

目录已损坏，无法再让sbt正常运行。

您可以执行

激活器“完全重新启动”

以查看是否有帮助吗？您使用什么命令行客户端-

cmd.exe

或类似于

cygwin

或

powershell

？你可能是在代理后面吗？我在用cmd.exe。没有代理。运行activator reboot full只会显示自述文本。我能够使用UI版本创建一个项目，因此我可能可以关闭此项目，但仍然存在一个奇怪的错误。您可以执行
