I am using following hco command for checking out the files from harvest for building project in Synchronize mode,
[b]<exec executable="C:\Program Files\CA\AllFusion Harvest Change Manager\hco.exe">
<arg line="-b '${application.harvest.broker}' -ced -usr '${application.harvest.userId}' -pw '${application.harvest.password}' -en '${application.harvest.environment}' -st '${application.harvest.state}' -vp '${application.harvest.projectdir}' -r -op '${application.harvest.pc}' -sy -cp '${application.checkedout.src}' -s '${application.harvest.filepattern}'"/>
</exec>[/b]
Untill yesterday it is working perfectly.
[i]Yesterday an update was happened to the harvest by the harvest admin, that is they added new process named "Check Out - Concurrent" to the harvest.[/i]
So after that if I am running my ant build using the above command (hco command in bold) results as following,
[b]I00060040: New connection with Broker HARVPROD established.
An invalid check out mode was given for process: 'Check Out - Concurrent'.[/b]
