### Architecture Overview

The library follows a layered architecture:

- **Context Layer**: `CIFSContext` interface provides the main entry point
- **Resource Layer**: `SmbResource` interface represents SMB network resources  
- **Protocol Layers**: Separate SMB1 (`jcifs.internal.smb1/`) and SMB2/3 (`jcifs.internal.smb2/`) implementations

whether that be from a workspace of an IDE, a local Maven repository, or a remote Maven repository. During development in an IDE we would need layered resolution approach that would allow resolution from the workspace, then the local Maven repository and then from any number of remote Maven repositories. During development from the command line we would need a layered resolution approach that would allow resolution from the local Maven repository and then from any number of remote Maven repositories.
