util

• org
  • abc
    • db
      • sql
        • Connection.java

but i开发者_高级运维n win7,look like this:

util

• org.abc.db.sql
  • Connection.java

they can auto merge empty package path

how can I merge empty package path in eclipse @ MacOS?

Open the little triangle menu on the top of the view and select filters. This will open a dialog window where you can configure several aspect of the view. One of them is "empty parent packages" which will hide those packages if it is enable.
