ScmWagon (Apache Maven Wagon 2.6 API)

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.

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

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.
