Subject Re: [vfs] Using VFS for FTP Access in Groovy
Date Wed, 23 Jan 2013 19:11:37 GMT
Hi Sven,
Do you have a runnable test for this?  I don't have access to an FTP server
at the moment so I can't really test this, but I ran this code snippet
against the local file system and it seemed to work properly:

    @Grab(group='org.apache.commons', module='commons-vfs2', version='2.0'),
import org.apache.commons.vfs2.FileObject;
import org.apache.commons.vfs2.FileSystemException;
import org.apache.commons.vfs2.VFS;
import org.apache.commons.vfs2.FileSystemManager;

FileSystemManager mgr = VFS.getManager();
FileObject file = mgr.resolveFile(System.getProperty("user.home"));
println file;
println file.getType();
    println it

One thing that occurred to me is that the grails classloader might be
loading an different version of the VFS library than your groovy script.

Gary, is there a way to output the VFS configuration (VFS version,
available FileSystems, and FileSystem versions)?
