不，这是不可能的。请投票支持此功能请求。请注意，您可以将多个项目作为模块添加到Intellij Idea项目中，以便能够在单个框架中查看它们。
BTW，有一个文档旨在帮助用户从Eclipse迁移到Idea - 请参阅此常见问题 - 你可能会发现它有帮助

No, it's not possible. Please vote for this feature request. Note that you can add your multiple projects as modules to Intellij Idea project to be able to view them in a single frame. BTW, there is a document intended to help users migrating from Eclipse to Idea - see this FAQ - you may find it helpful
