Execute ANT Tasks Remotely
Prerequisites:
  1. To execute ant targets remotely, we need to have ssh enabled on target machine.
  2. Need to have jsch-xxxx.jar file placed at <antDir>\lib. Can download this jar file @ https://ant.apache.org/manual/install.html#librarydependencies 
 
Execute ant targets remotely without using CNL:
  • Execute ant target present on target machine using following target on source machine:
        <target name = "executeAntRemotely">
            <sshexec host="${target.host}"
            username="${loginUserName}"
            password="${loginPassword}"
            trust="true"
            Command="ant ${targetName} -buildfile ${buildfile} -D<key>=<value> ...."/>
        </target>
 
  • Execute batch file present on target machine using following target on source machine:
        <target name = "executeBatchRemotely">
            <sshexec host="${target.host}"
            username="${loginUserName}"
            password="${loginPassword}"
            trust="true"
            Command="<batch file location eg--C:/HudsonRoot/SIQA/ALF_JENKINS/Executables/${batchFileName} >"/>
        </target>
  • NOTE: Login credentials are of target machine.
 
Execute ant targets remotely using CNL on source and only Ant on target:(This approach can be used if you dont want to use CNL on target)
 
Prerequisites On Source Machine:
  • CNL checkout is required.
  • Install STAF and set system path variable.
  • Following parameters may have to be passed for CNL execution:
  • ant.target.name = <ant target name>
  • ant.xml.file = <full path to build file name ex C:\JobTargets.xml>
  • machine.alf.home = <full path to CNL checkout folder>
  • WORKSPACE = <workspace>
  • machine.name = <CNL.host, host name where CNL is running>
  • Rest all remains same, should have following ant target in source machine

        <target name = "executeAntRemotely">
            <sshexec host="${target.host}"
            username="${loginUserName}"
            password="${loginPassword}"
            trust="true"
            Command="ant ${targetName} -buildfile ${buildfile} -D<key>=<value> ...."/>
        </target>

Explaination:

  • <host>: Target host name.
  • <username>: User name for target host.
  • <password>: Password for target host.
  • <trust>: This trusts all unknown hosts if set to yes or true.
  • <Command>: Will execute this command on target host after successful login.
