Unable to build openfire pade plugin

We are trying to build the openfire pade plugins following the instructions on github: https://github.com/igniterealtime/openfire-pade-plugin
We have modified the url to point to our server but when we try to build the plugins we see the following errors:
“[ERROR] [ERROR] Some problems were encountered while processing the POMs:

[ERROR] The build could not read 5 projects -> [Help 1]”
Our build is coming from a windows machine that has maven 3.6.3 and the latest java jdk.
Any help would be greatly appreciated.
