Probably exist an error in your workflow.bpmn file or in your service-context.xml (where you set the configuration of deploy). Can you specify the error or attach your console log file?
As the log says, the error is on the file scWorkflowModel.xml, may be for a bad write of a character or tag (i.e. missing closing tag), or the order of sentences in the XML (i.e. The declaration of a type or aspect).
Please, if you not find the error, attach your scWorkflowModel.xml file.
