The licenseFile parameter is not working for non-standard file paths. From the Exception it looks like the file name is missing from the target path. (Plugin version 1.0.12).
In addition, the use of documentationFile parameter is a bit vague. Docs say [quote]the path to the directory where your documentation can be found[/quote] but it looks like the plugin always copies the /doc folder, and this parameter is only used in the generated xml file, so it should point to a .html file inside the doc folder.
