I got past this issue. Here's what I did, in case anyone else has the same
problem. First, I upgraded my plugin's dependency to ruby-runtime 0.9 and I
upgraded jpi's development Jenkins instance to 1.455. I set up my action like
so:
class BundledGems
include Jenkins::Model::Action
# ...
end
and I registered a proxy for it by hand:
class BundledGemsProxy
include Jenkins::Plugin::Proxies::Action
proxy_for BundledGems
end
Then in my publisher's perform method I did what I had outlined in my previous
message:
def perform(build, launcher, listener)
# ...
build.native.add_action(Jenkins.plugin.export(BundledGems.new(...)))
end
I'm now having a problem rendering the view for the action
(org.jruby.exceptions.RaiseException: (NameError) uninitialized constant
Rack::VERSION) but I'll post with more details if I can't figure it out.
Thanks,
Rhett
