groovyとJackrabbitでWebDAVサーバ上のリソースを移動する

groovyとJackrabbitでWebDAVサーバ上のリソースを移動するには、以下のコードを実行します。

@Grab(group='org.apache.jackrabbit', module='jackrabbit-jcr2dav', version='2.2.9')

import org.apache.commons.httpclient.auth.*
import org.apache.commons.httpclient.*
import org.apache.jackrabbit.webdav.client.methods.*
import org.apache.jackrabbit.webdav.*

// WebDAV URL
baseUrl = "http://localhost:8080/repository/default"
oldpath = "/" + java.net.URLEncoder.encode("テスト", "UTF-8")
newpath = ""
oldurl = baseUrl + oldpath
newurl = baseUrl + newpath
filename = "サンプルファイル.txt"

try
{
  client = new HttpClient()
  client.getState().setCredentials(AuthScope.ANY, 
    new UsernamePasswordCredentials('username', 'password'))

  method = new MoveMethod(
    oldurl + "/" + java.net.URLEncoder.encode(filename, "UTF-8"),
    newurl + "/" + java.net.URLEncoder.encode(filename, "UTF-8"),
    false /*= overwrite */
  )
  client.executeMethod(method)
  println(method.getStatusCode() + ":" + method.getStatusText())
}
catch(HttpException ex){
  println ex
}

動作環境
