[Windup-users] Stable version throws NullPointerException, no usable instructions for non-stable version

[Lincoln Baxter, III]

Hey Steve,

Sorry for the late reply. Your message got caught in our moderation filter
for a while :/ The Windup 2.0.0.Alpha stuff is very work-in-progress. You
are probably better off building the old Windup 1.x branch from the legacy
repo (which I believe includes the fix for the NPE you are running in to.)

https://github.com/windup/windup-legacy

We hope to have a preview release of windup 2 out in a few months.

~Lincoln
