我目前正在使用Windows 7,64位。我用spring roo安装了一个干净版本的sts 2.7.2，起初一切都在起伏不定。后来，我尝试安装spring roo 1.1.5的独立版本。一旦我输入roo，我就开始获得以下堆栈跟踪：

我试图搜索这个但找不到任何东西，所以我安装了1.2.0M1版本但是我遇到了同样的问题。过了一会儿，我放弃了，并试图继续使用生活在之前工作的ide中的roo shell。然而，我的想法似乎不再起作用了。当我尝试在现有的roo项目上执行任何命令或尝试创建一个新项目时，就会永远挂起。 为了修复它，我试图删除sts，重新安装它，重新启动我的电脑，清理注册表，安装不同的版本，如1.7.1，将我的jdk从1.6_22更改为1.6_27但我现在总是遇到同样的问题。
我已经阅读了很多关于spring roo的内容，并且非常期待开始使用它，但是我没有想法。
我有什么办法可以让它再次运作吗？
提前感谢您的帮助。
