Package already exists. Note:views might filter empty parent packages. Solution

2 packages built in eclipse

Com.sys.dao and Com.sys.dao.imp

Later deleted the Com.sys.dao, Com.sys.dao when the package will prompt the package already exists

So is this package still in the form of a folder in the disk workspace?

We find the workspace and we find out that this bag really doesn't exist.

Well, the thing is this bag really doesn't exist, but eclipse is not allowed to build

In this project to find a random bag, build a class file and the first line automatically generated

The package declaration is changed to the package we want to create. Here I need to change into package com.sys.dao;

At this point eclipse will prompt for the error (nonsense) and we'll use it for this classic quick fix

This does not let us build, we can not find the Com.sys.dao bag and magically appeared we will move to the good
