[Jython-users] Jython and Nailgun?

[Mike R. <mro...@ya...>]

Dear all,
I have managed to get this working... and it makes the startup time basically disappear!

Using Nailgun in Eclipse for Java and Jython

But then I found there was a fly in the ointment: old versions of the working files appear to get cached... and cached very persistently.

Clear some stuff from Nailgun cache (usage: Jython)

As mentioned at the end of this post I have now looked at the source code... but it is pretty hard stuff: both Java and C code is involved, and somewhat beyond my pay grade.
Is there an alternative to Nailgun perhaps?  Or has anyone succeeded with Nailgun?

I used Nailgun in the past, but not with Jython.

Did you try stopping the Nailgun server using ng-stop?

Here's essentially the same question, unanswered. If we learn the
answer, it would be good to add an answer there, too.

Here's a project in Ruby that uses Nailgun.
https://svn.apache.org/repos/asf/buildr/tags/1.3.3/addon/buildr/nailgun.rb
I don't read Ruby, but it seems they do this, whatever that is:
          Nailgun.ng.server.cached_runtimes.clear
          Nailgun.ng.server.cached_stamps.clear
          Nailgun.ng.server.loaded_times.clear
          info "Cleared all cached runtimes"

Thanks...
In fact that link you give to SO is the one I put in my original post... it's the question I posed a couple of days ago.
Thanks for the link to Ruby... but the message "Cleared all cached runtimes" looks a bit like it's doing what I don't want it to do: to clear *everything*.  I only want certain working files, which are subject to change, to be cleared from cache.  If you clear everything then presumably the startup time is going to be the normal, lengthy Jython startup time each time you run your app/UTs...
