Body:
I've also had several reports like this on my current project. I haven't been able yet
to tell whether the problem was due to:
- a bad machine date (either local machine or remote repo machine)
- a web server not supporting if-modified-since
- a bug
I have looked at the source code and couldn't find any reason why it wouldn't work as
expected (in HttpUtils, from CVS HEAD):
[...]
boolean hasTimestamp = false;
if ( useTimestamp && destinationFile.exists() )
{
timestamp = destinationFile.lastModified();
hasTimestamp = true;
}
[...]
if ( useTimestamp && hasTimestamp )
{
connection.setIfModifiedSince( timestamp );
}
[...]
if ( httpConnection.getResponseCode() ==
HttpURLConnection.HTTP_NOT_MODIFIED )
{
return;
}

Description:
I have the problem that I have created fresh and most-recent new snaphot
jars in my _local_ repository (lets say in project A).
Now I like to test them inside Project B with depends upon this
snapshots jar!
Problem: In online mode, maven downloads the snapshots jars from it's
remove repository and overwrites the fresh most-recent jars which I just
installed into my local repo.
As a workaround, of course I can run in offline mode, but this has other
drawbacks (e.g. if meanwhile project B needs to download a new jar).
Is there any option inside maven to prevent such a behaviour in online
mode?? IMHO maven should replace the snapshot jar only if the remote
version is _really_ younger than the one on my local harddrive!
You help and comments highly appreciated - I *really* need this...
I am sorry but I was unable to provide a patch - have no idea where to check the maven
sources. If one helps me a little and tells me which classes do the download, I am
looking into the source myself.
Thanks in advance,
Martin
