Auto FTP

Auto FTP will listen on a connection for new files -- files you're interested in -- and will automatically add them to a download queue and process them. This means you can run this application, set up host information -- including file filters -- then leave it running in the background. It works by:

• Connecting to the host at a [user specified] interval.
• Navigates to a user specified remote directory.
• Scans all files that have been modified since last scan.
• Runs files through the filter list, picking out relevant files.
• Adds selected files to a download queue
• Downloads files, one at a time to a user specified local directory
• Closes connection once all files have been downloaded and updates the last scan date-time.

Project Setup

This is a Gradle based project and includes everything you'll need to get its dependencies. The Gradle Wrapper that has been included means you don't need to have Gradle pre-installed before you get the project. It will download any Gradle-specific libraries itself. Just do the following and Gradle should build the project for you:

UNIX/OS X:

./gradlew build

Windows:

gradlew build

This project is fully tested and all tests can be run via Gradle:

gradlew test

If you use Eclipse, it may be worth also running the Eclipse-specific tasks as well to help set up your .project:

gradlew eclipse

Quick FTP Example

Client client = new ClientFactory().createClient(ClientType.FTP);
client.setHost("a.host.name");
client.setPort(21);
client.setCredentials("username", "password");

Connection connection = client.connect();
connection.setRemoteDirectory("files/todownload");
  
List<FtpFile> remoteFiles = connection.listFiles();
  
for (FtpFile file : remoteFiles)
    System.out.println(file.getName());
    
client.disconnect();

Note: The protocol behind the client is defined via the factory. If you want an FTP connection, then use ClientType.FTP. If you want it to be SFTP, then use ClientType.SFTP. The protocol type doesn't affect any of the above code syntax; just how it behaves.
