Usage

From source file:com.streamsets.pipeline.stage.origin.remote.FTPRemoteDownloadSourceDelegate.java

@Override
String archive(String fromPath) throws IOException {
    if (archiveURI == null) {
        throw new IOException("No archive directory defined - cannot archive");
    }/*from  w w w . j  a  va2 s.co m*/

    String toPath = archiveURI.toString() + (fromPath.startsWith("/") ? fromPath.substring(1) : fromPath);

    FileObject toFile = VFS.getManager().resolveFile(toPath, archiveOptions);
    toFile.refresh();
    // Create the toPath's parent dir(s) if they don't exist
    toFile.getParent().createFolder();
    getChild(fromPath).moveTo(toFile);
    toFile.close();
    return toPath;
