Subject [jira] Created: (WAGON-328) Allow putDirectory to continue even if an individual file transfer fails
Date Sun, 22 May 2011 14:57:22 GMT
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.
