Remove double spacing in eclipse

Question

I imported my project into eclipse and it became double spaced. Does anyone know how to fix this?

Tried:

Find: [\t ]+$ 
Replace With: Nothing //error: incompatible line delimiter

Find: \s*\n 
Replace With: Nothing //error: incompatible line delimiter

Find:  ^\s*\r?\n
Replace With: /R //error: incompatible line delimiter

Find:  ^\s*\r?\n
Replace With: nothing //string not found

Find:  (.)\r\n(.)
Replace With: nothing //string not found

File > Convert Line Delimiters to > Windows //no changes

Source > Apply Formatting //grayed out

CTRL + Shift + F //doesn't remove double spaces

Answer 1

In project properties I went to the flexFormatter and changed the option keep this many blank lines to 0.

Answer 2

Have you tried (with regex check on of course):

Find: ^\s*\r?\n

Replace with: \R

This finds one or double lines and replaces it with one line.
