Hi,

The new Jenkins UI looks nice, and will be a big improvement over the
existing UI.

The original selling point of Jenkins was that even with the simplistic
forms-based UI,
someone could fill out a relatively simple form, and have a continuous
integration pipeline.
I have met people who were general devops and scripting people, and could
use Jenkins quite nicely.

While I understand the motivation for Pipeline (previously known as
Workflow), I can't say I'm very happy with the results.

Here are some of the pain points I've encountered with Pipeline scripts:

   - Other than the most trivial of scripts, you need to be a knowledgable
   Groovy programmer.  For example, to make a global variable, you need to use
   a @Field.  (What?!)  Most scripting and devops people that I know don't
   really know Groovy.
   - Documentation for Pipeline scripts isn't that great (although it has
   definitely been improving).  In all honesty, I cannot point a junior
   scripting person to write a good Pipeline script for developing a build
   Pipeline.
   - The durable task plugin which invokes shell commands on Unix, and
   batch jobs on Windows goes through an elaborate method for invoking shell
   commands.  It is very, very difficult to grab the exit status of commands,
   stderr, stdout, etc.  For a while, these wrappers would do things like not
   detect when a command had terminated, etc. (Looks like this has been fixed
   now)
   - It is very hard to figure out how to cancel a running Pipeline job.
   The UI link to "Click here to cancel" a Pipeline job is hidden in the build
   output, and often doesn't work.

I understand that Jenkins is going through a big transition period.
Hopefully at the end of the road, things will be much better.
However, at this point in time, I would say that in many ways, the current
direction is *worse* than the old way of doing things with the old Jenkins
UI.
The old way has problems, but it was easy to figure out, and didn't have a
lot of these intermediate layers that try to abstract things out,
but make things harder to figure out what is going on.
