Eclipse 建包时出现 Package already exists. Note: Views might filter empty parent 的解决方案

有人喜欢在编程中把所有的包都建好以后再开始编程,就难免会在建包的时候出现:
Package already exists. Note: Views might filter empty parent.
这样的错误提示。错误是因为该包你已经建了,因为它是一个空包(即不包含类,并不是不包含包),所以未显示出来。要显示出来的话,你可以在【Package Exporer】中将【Package Presentation】选为“Hierarchical”,就可以看到你已经建的空包了。因为该模式下包是按树的结构显示的。
这样你就不难发现在Eclipse中当你建包时一个“.”就会帮你建一个文件夹,这里的包其实就是文件夹的概念,因此先建了子文件夹再去建父文件夹,当然会出错,因为它已经存在了!
