How the plugin extension DSL will look like for Groovy VFS. No need to struggle with Apachae VFS vfs-provider.xml files

vfs-plugins.groovy

import org.ysb33r.groovy.dsl.vfs.VFS

def vfs = new VFS() 

// ---------------------------------
// Adding new providers with schemes
// ---------------------------------
vfs {
  extend {
    // Adding provider with no external dependencies 
    //   (className must be on classpath)
    provider className : 'org.apache.commons.vfs2.provider.gzip.GzipFileProvider',schemes : ['gz']

    // Adding provider that also relies on other libraries 
    //   (className and dependsOnClasses must be on classpath)
    provider className : 'org.apache.commons.vfs2.provider.tar.TarFileProvider',
            schemes : ['tar'],
            dependsOnClasses : ['org.apache.commons.vfs2.provider.tar.TarInputStream']
    
    // Adding provider that requires other providers to already be in place
    //   (className must be on classpath)
    provider className : 'org.apache.commons.vfs2.provider.tar.TarFileProvider',
            schemes : ['tgz'],
            dependsOnSchemes : ['tar','gz']
  }
}

// --------------------------------------
// Adding operation providers for schemes
// --------------------------------------
vfs {
  extend {
    operationProvider className : "acl.AclOperationsProvider",
        schemes : ["s3","aws"]
  }
}

// --------------------------------------
// Adding maps
// --------------------------------------
vfs {
  extend {
    // Adding a MIME Type mapping
    // Second parameter is te scheme
    mimeType 'application/zip', 'zip'
    
    // Adding a file extension mapping
    // Second parameter is the scheme
    ext 'gzip', 'gz'
  }
}
