Intellij Idea and auto formatting : spaces

Question

I noticed Intellij Idea auto formatting removes spaces from blank lines. In an example below spaces are shown with "_"

__line1
__
__line3

And idea makes that:

__line1

__line3

How can I turn that off? It prevents using subversion.

Push

Answer 1

This is found under:

• Windows: File > Settings > Editor > General > Strip trailing spaces on Save
• MacOS: IntelliJ IDEA > Preferences > Editor > General > Strip trailing spaces on Save

IntelliJ gives you the ability to search in the Preferences dialog. You can narrow down the list of options by searching for "trailing", for example.
