Remove trailing whitespace on save in IntelliJ IDEA 12

Question

Is it possible to remove trailing whitespace automatically on save in IntelliJ IDEA? I know there are some workarounds, for example, using git to trim the whitespace on commit.

Answer 1

Don't know about 12, but there's the following setting in 13:

Settings → Editor → Strip trailing spaces on Save

As of IntelliJ 2017.2 it's under

Settings → Editor → General → Strip trailing spaces on Save
