SBT Error: “Failed to construct terminal; falling back to unsupported…”

Question

I have run into an ERROR with SBT today. It can best be shown with the sbt sbt-version command:

Run on 5/29/17:

eric@linux-x2vq:~$ sbt s         


        

Answer 1

I found the package which causes this issue: ncurses. I downgraded ncurses to version ncurses-6.0+20170429-1 (I am using Arch Linux) and SBT starts just fine.

Steps for Arch Linux:

cd /var/cache/pacman/pkg
sudo pacman -U ncurses-6.0+20170429-1-x86_64.pkg.tar.xz # or some other older version

Steps for Mac: see https://github.com/jline/jline2/issues/281

I think this issue was introduced with ncurses version 20170506, see: http://invisible-island.net/ncurses/NEWS.html#index-t20170506

+ modify tic/infocmp display of numeric values to use hexadecimal when
      they are "close" to a power of two, making the result more readable.

I filed an issue on the SBT issue tracker: https://github.com/sbt/sbt/issues/3240

Edit: SBT version 0.13.16 includes the fix for this problem.
