The settings.gradle file contains an unconditional include of 'go.graphics.android' which breaks the build process when trying to build the swing ui on a system with no Android installed (tested on Ubuntu 16.04).
Removing the line fixes the issue.
'go.graphics.android' is included anyway in line 25 if Android is present on the system.
