Eclipse code checkstyle indentation module in java?

Question

i am using checkstyle.

i want to configure checkstyle so that code indentation use 2 space. For example :-

while(condition) {
  if(condition) {
    while(condition)
  }
}

Please note the inentation is using 2 spaces. For example :- if block startted after 2 spaces.

i tried

     <module name="Checker">
       <module name="Indentation">
        <property name="basicOffset" value="2"/>
        <property name="caseIndent" value="2"/>
       </module>
    </module>

But it does not give warning on applying checkstyles when i add 4 spaces instead of 2 like below

 if(condition) {
        while(condition)
      }

I am not getting whats the issue?

Checkstyle inspects code that you have. It doesn't control formatting. You need to control the formatting through Eclipse.

Window -> Preferences -> Java -> Code Style -> Formatter

is where you want to start poking around.

EDIT after update of question:

The Indentation module belongs under the TreeWalker module, not the Checker module.

Thats a valid point that i need to use formatting if i want to do indentation. Actually i want to display warning if somebody adds 4 spaces instead of 2 space on applying checkstyles.I updated my question.
