How does one show trailing whitespace in eclipse?

Question

I'm looking for something like (setq show-trailing-whitespace t) in emacs, where all of the trailing whitespace is blindingly clear, ie highlighted. My searches for this kind of option have mostly turned up examples of removing all trailing whitespace, which is not at all what I'm looking for.

Answer 1

Click on:

Window > Preferences > General > Editors > Text Editors 

Then click on the link "whitespace characters" to specify what should be shown.

Answer 2

What I settled on for this takes a plugin but isn't bad. Then your trailing whitespace will show up as an eclerror/warning in the file.

1: eclipse checkstyle plugin 2: make a checkstyle config as generous as you want. if you ONLY want trailing whitespace:

<module name="Checker">   <module name="TreeWalker">     <module name="Regexp">       <property name="format" value="[ \t]+$"/>       <property name="illegalPattern" value="true"/>       <property name="message" value="Trailing whitespace"/>     </module>   </module> </module>
