Body:
So it turns out it was a class from a Maven plugin of minen that was printing
the ugly stack trace, not Maven itself. However, I'd still like to keep this
issue open as an ER to have HttpUtils.getFile() either not throw an exception
for a 304 or to throw something more strongly typed than an IOException (e.g.
NotModifiedException). My code looks like:
try
{
...
if ( meterType != null )
{
HttpUtils.setMeterType( meterType );
}
long preModTime = artifact.getFile().lastModified();
HttpUtils.getFile( url,
artifact.getFile(),
IGNORE_ERRORS,
USE_TIMESTAMP,
m_project.getContext().getProxyHost(),
m_project.getContext().getProxyPort(),
m_project.getContext().getProxyUserName(),
m_project.getContext().getProxyPassword(),
loginHost,
loginDomain,
USE_CHECKSUM );
long postModTime = artifact.getFile().lastModified();
artifactDownloaded = artifactDownloaded || postModTime > preModTime;
artifactFound = true;
if ( !artifact.isSnapshot() )
{
break;
}
}
catch ( FileNotFoundException fnfe )
{
// ignore
}
catch ( Exception e )
{
LOG.error( "Error retrieving artifact from " + url );
e.printStackTrace( );
}
In the last catch clause, I don't want to log an error in the case of a 304,
but there's no way for me to tell that it was a 304, and not a real error
(except by doing e.getMessage().indexOf("304"), but I'd rather not stoop to
that).
Thanks,
Ian

My remote repo is hosted on an IIS server. When it returns status code 304 (Not
Modified) for certain jars, Maven dumps a big ugly stack trace (even without
debug turned on). See below...
