Allow putDirectory to continue even if an individual file transfer fails
------------------------------------------------------------------------
Key: WAGON-328
URL: http://jira.codehaus.org/browse/WAGON-328
Project: Maven Wagon
Issue Type: Improvement
Components: wagon-webdav
Affects Versions: 1.0-beta-8
Reporter: Andrew Phillips
The current WebDAV wagon implements putDirectory as a recursive sequence of
individual put commands for the individual files. This means that failure of an
individual put will abort the entire putDirectory.
This, of course, is generally correct and desired behaviour. However, in a few
cases it may not be critical that all files in a directory are correctly
uploaded. The use case in mind here is uploading Maven sites to not 100%
reliable DAV resources, e.g. Google Code (see also [WAGON-319]).
The request would be thus to add a "continueOnFailure" option (or similar)
which would not throw a TransferFailureException if put fails, but instead log
a warning or similar. This option would be false by default.
Admittedly, the better/"correct" place to address this issue would be in the
code that *calls* the wagon (in the case of this example, in the Maven Site
plugin), because it can make the context-specific decision of whether to be
lenient with errors or not.
However, there is no "putDirectoryLeniently" wagon method that the parent can
call, and this use case does not seem significant enough to merit changing the
wagon interface.
