eclipse dart工作区中的可见包文件夹

Question

我在Eclipse luna中使用dart 1.9.00_dev。 在我从这个网站https://pub.dartlang.org/packages/json_object安装软件包之前，Everthing工作正常 该软件包改变了我的整个工作区，使所有软件包都可以看作是＆＃39; raw＆＃39;工作区中的文件夹。以前，只有突出显示的包存在。

我从我的Windows用户目录中移除了.dartium和pub文件夹以及项目中的所有包，然后先pub get执行pub upgrade。但是包文件夹仍然可见。它们填满了我的工作空间，让它看起来很不雅观。

如何防止这些额外文件夹可见。删除有问题的json_object，删除pub，.dartium目录以及项目中的所有包都不起作用。

请参阅附图。
