How to repeat text matched by a regex?

I'm trying to add log4j to a legacy software using eclipse search/replace.

The idea is to find all class declarations and replace them by, the declaration itself plus the definition of the logger in the next line.

search 

".*class ([A-Z][a-z]+).*\{"

replace: 

"final static Logger log = Logger.getLogger($1.class);"

How can I prepend the matched pattern (the class definition) to the replace string?

I think you need this:

search:

(.*class ([A-Z][a-z]+).*\{)

replace:

$1\Rfinal static Logger log = Logger.getLogger($2.class);

You can always capture the whole thing and put it in. The inner capture group lives in a second backreference.

Find:

(.*class ([A-Z][a-z]+).*\{)

Replace with:

$1 final static Logger log = Logger.getLogger($2.class);
