[ros-users] Groovy EOL Complete

[Tully Foote]

Hi Everyone,

I'm writing to highlight another milestone. As we have have now released
indigo and are looking forward to Jade, it is time to retire Groovy.

Groovy was first officially released at the end of 2012, but work toward
the release had been started in early 2012.[1] During it's life cycle
Groovy almost double the number of packages released reaching a maximum of
900.

Reviewing the history of the rosdistro repository which contains the
release metadata reveals that there was 2912 commits from 127 contributors
over the history of the Groovy release. This represents the maintainers
making the releases and does not count the many more contributors to the
source code of the individual packages. There were commits on 612 different
days over the 794 days tracked in this repository. This means on average
there were releases of groovy packages more than 5 days per week. For a
quick visualization of the activity on the repository we've put together a
rendering of commits to the groovy subdirectory: https://vimeo.com/108642560
(These statistics only count catkin based releases, not the 178 rosbuild
packages indexed separately.)

As you may have already noticed, last week we disabled all the groovy jobs
on the farm. We have kept them there for reference but do not intend to
reenable them. Along those same lines, we can accept pull-requests to keep
source builds working on groovy(such as  if a repository is relocated to a
new host), but cannot accept pull-requests for new groovy releases.

As always we'd like to pay trubute to the hundreds of people who put the
time in to make groovy happen. It would not have happened without your
efforts.

You ROS Release Team
