Sadly, AppScan standard doesn't support a scan file (or scan template) whereby you can point it at a host and let it run.  The scan template is as step in that direction because the AppScan Standard application allows you to change the target host and save the file.

Given this, I tend to create a scant and use that to customize the scan to a particular target host and then save it as a scan file specifically for that host.

It would be fantastic if this plugin allowed us to specify a scan file instead of a scant file.  Or, if somehow the plugin could update the scant file within Jenkins for the target host and then use that local version to upload to ASoC.
