How to SFTP & FTP with Ant Tasks

I will explain, how you can send files using ANT scipt over SFTP protocol.

Until i find how to use sftp protocol, I googled also ftp protocol. I will explaint it firstly,

If you want to use FTP protocol, you may use <ftp> tag of commons-net-1.4.1.jar. To do this :

• Download commons-net-1.4.1.zip jar from here.
• Add this jar to your ant lib folder using explorer or Define it from eclipse, “Window > Preferences > Ant > Runtime > Global Entries > Add Jar “
• If you do not add this jar, you will get “Could not create type ftp due to java.lang.NoClassDefFoundError: org/apache/commons/net/ftp/FTPClientConfig” error.
• Then write your ftp command to ant script

<target name="deploy" description="War is deploying">
 <ftp server="${ftp.host}" port="${ftp.port}" remotedir="${ftp.remotedir}" userid="${ftp.userid}" password="${ftp.password}" depends="yes">
      <fileset dir="${maven.build.dir}/war/" />
 </ftp>
</target>

• If you use this method for SFTP (Port:22), You will get “error during FTP transfer: org.apache.commons.net.MalformedServerReplyException:
  Could not parse response code. Server Reply: SSH-1.99-OpenSSH_3.9p1” error.
•  So, this method is valid for only FTP protocol.

 

After the experience below, I keep searching and find SCP task (min Ant 1.6).

• Download jsch.jar0.1.42 or later from here
• You may see examples in the page. This task can used to transfer any data from remote and local machine.
• Add this jar to your ant lib folder using explorer or Define it from eclipse, “Window > Preferences > Ant > Runtime > Global Entries > Add Jar “
• Then write your scp command to ant script

<target name="deploy" description="War is deploying">
    <scp file="${war.filepath}" sftp="true" trust="true" todir="userid:password@host:/to/dir/" />
</target>

• If you do not add trust=”true” property, you will get “com.jcraft.jsch.JSchException: reject HostKey” error.

 

Good coding
