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.
