Hi Kannan, there is not enough information, but maybe stcheckout was a batch file? in any case this is how you would checkout files using starteam command line:  admhelp.microfocus.com/.../Check Out Files co.htm

Thank you for the quick response. I will check the link which you shared,

To give you more information, we are using ant build to checkout from StarTeam. and I suspect ant library has this StarTeam Task  library which is not compatible with the latest version of StarTeam client. Please find the below checkout target used. 

<target name="getScripts" depends="cleanScripts">

<!-- This will check out the build scripts -->
<stcheckout
servername="${build.scripts.st.server.name}"
serverport="${build.scripts.st.server.port}"
projectname="${build.scripts.st.server.project}"
viewname="${build.scripts.st.server.view}"
username="${build.scripts.st.server.username}"
password="${build.scripts.st.server.password}"
createworkingdirs="false"
deleteuncontrolled="false"
recursive="true"
rootlocalfolder="${main.build.home}"
rootstarteamfolder="/buildscripts"
/>

<!--This will check out the build scripts for particular project -->
<stcheckout
servername="${build.scripts.st.server.name}"
serverport="${build.scripts.st.server.port}"
projectname="${build.scripts.st.server.project}"
viewname="${build.scripts.st.server.view}"
username="${build.scripts.st.server.username}"
password="${build.scripts.st.server.password}"
createworkingdirs="false"
deleteuncontrolled="false"
recursive="true"
rootlocalfolder="${application.build.home}"
rootstarteamfolder="/buildscripts/build_${application.name}"
/>
</target>

-- However,  it is working fine with ANT version 1.8.2. But, we would like to update ANT latest version and endup getting exception.

Thanks,

Kannan

Sounds like stcheckout has been deprecated in ant. We do have a plugin for Jenkins, or you can use stcmd/stcmdex to do the same as stcheckout

Thank you Danielle, will try to use stcmd and update if any issues.
