Re: [ddsteps-user] about the null pointer exception of ddsteps-1.1

[Adam S. <ada...@gm...>]

Hi there!

There's a known bug using that combination, so please consider using  
the DDSteps 1.2-rc3 (it's good) found in our maven repo.

I'm building a new site for DDSteps, and I've made the maven install  
guide a bit clearer. Have a look here:

Cheers
