Class ScmWagon

java.lang.Object

org.apache.maven.wagon.AbstractWagon

org.apache.maven.wagon.providers.scm.ScmWagon

All Implemented Interfaces:

Wagon

public class ScmWagon
extends AbstractWagon

Wagon provider to get and put files from and to SCM systems, using Maven-SCM as underlying transport.

TODO it probably creates problems if the same wagon is used in two different SCM protocols, as instance variables can keep incorrect state. TODO: For doing releases we either have to be able to add files with checking out the repository structure which may not be possible, or the checkout directory needs to be a constant. Doing releases won't scale if you have to checkout the whole repository structure in order to add 3 files.

Description copied from interface: Wagon

Returns a List of strings naming the files and directories in the directory denoted by this abstract pathname.

If this abstract pathname does not denote a directory, or does not exist, then this method throws ResourceDoesNotExistException. Otherwise a List of strings is returned, one for each file or directory in the directory. Names denoting the directory itself and the directory's parent directory are not included in the result. Each string is a file name rather than a complete path.

There is no guarantee that the name strings in the resulting list will appear in any specific order; they are not, in particular, guaranteed to appear in alphabetical order.

Overrides:

getFileList in class AbstractWagon

Parameters:

resourcePath - directory to list contents of

Returns:

a List<String> with filenames/directories at the resourcepath.

Throws:

TransferFailedException - if there's an error trying to access the remote side

ResourceDoesNotExistException - if destinationDirectory does not exist or is not a directory

AuthorizationException - if not authorized to list the contents of the directory
