how to search and replace 2 lines via eclipse?

Question

I would like to search all files via eclipse which contain the following 2 lines

    @Length(max = L_255)
    private String description;

and replace it with 
    @Length(max = L_255, message="{validator.description.len}")
    private String description;

Answer 1

Select the folder that contains all your files and press Ctrl-H.

Answer 2

Try PilotEdit Lite, it is FREE. It is a good tool to replace multi-line text. http://www.pilotedit.com

Answer 3

Search are multi-line by default in Eclipse when you are using regex:

(\@Length\(max = L_255)\)([\r\n\s]+private)

I would like to add "private String description;"

(\@Length\(max = L_255)\)([\r\n\s]+private\s+?String\s+description\s*?;)

replaced by:

\1, message="{validator.description.len}")\2

It works perfectly in a File Search triggered by a CTRL-H.
