Copy multiple files to FTP parallely with ant?

i have to copy a large file via FTP. For faster upload i have split the file into 10 parts and I'm trying to upload the splits using the target of ant.However i found that all the splits are queued and are not uploaded parallelly. Does ant have any option to initiate parallel uploads ? For.eg in Filezilla you can have set the max parallel upload limit to 10, which starts all the uploads parallelly ?

Try wrapping your tasks in the <parallel> task. When your build file looks similar to

<ftp ...transfer split1 />
<ftp ...transfer split2/>
...
<ftp ...transfer split10/>

just put these targets in a parallel element:

<parallel>
  <ftp ...transfer split1 />
  <ftp ...transfer split2/>
  ...
  <ftp ...transfer split10/>
</parallel>

In case you may want to limit the number of parallel tasks (i.e. file transfers) you can set the threadCount property, e. g.

<parallel threadCount="4">

lets a maximum of 4 threads run in parallel.

If you need to handle several tasks after each other, e.g. transfering a file and then logging that the file was transferred, you can cluster those tasks in a <sequential> task:

<parallel>
  <sequential>
    <ftp ...transfer split1 />
    <echo>transferred file 1</echo>
  </sequential>
  <sequential>
    <ftp ...transfer split2/>
    echo>transferred file 2</echo>
    ...
  </parallel>
