Debug As unable to attach

[mikewindlake]

Hi

We are a rookie team and trying to use Java. Also new to Eclipse and Java. The latest image and JRE have been installed. The driver station and Dashboard work. The Run As works fine, the program downloads. But...

The Debug As will not work. I had this working for 2016 version (trying to get up to speed last year). This is happening on both of the computers so it must be something we've missed.

I've searched about but having found anything related. Help would be much appreciated.

The Error Log is
