Hello,

I tried to use this tool against following projects

https://mkyong.com/struts/struts-hello-world-example/
https://mkyong.com/struts/configure-a-welcome-page-in-struts/

For both of above projects, only empty directories with spring libraries were created.

On the console, following error gets logged.
