The getIfNewer method fails to work if file doesn't exist locally and the Last-Modified header isn't sent by the server
-----------------------------------------------------------------------------------------------------------------------

         Key: WAGONHTTP-5
         URL: http://jira.codehaus.org/browse/WAGONHTTP-5
     Project: wagon-http
        Type: Bug

    Versions: 1.0-alpha-3    
    Reporter: Kohsuke Kawaguchi


The code doesn't work correctly if the following two conditions are met simultaneously:

  (i)  the local file doesn't exist --- hence the timestamp parameter is 0
  (ii) the remote server doesn't send the "Last-Modified" header.

Since the lastModified variable is initialized to 0 in line 355, if the above two conditions are met,
the following if statement at line 371 evaluates to false:


*            if ( timestamp < lastModified )
             {
                 retValue = true;

and therefore the file won't be downloaded, causing the dependency to fail.

This used to work with Maven 1.0.2.

To fix this problem, initialize the lastModified variable to 1.
