Jesse has been developing Jenkins core and plugins for years.
He is the coauthor with Kohsuke of the core infrastructure of the Pipeline system.
Cleaning up technical debt is a perennial topic among Jenkins core developers,
and one of the most visible issues is the use of obsolete and/or forked third-party libraries.
In a world where Dependabot is offering updates to libraries released just hours before,
it is unpleasant to be working with dependencies that are many years old.
Since large organizations in particular are unhappy to install...
I am happy to report that JEP-222 has landed in Jenkins weeklies,
starting in 2.217.
This improvement brings experimental WebSocket support to Jenkins,
available when connecting inbound agents or when running the CLI.
The WebSocket protocol allows bidirectional, streaming communication over an HTTP(S) port.
While many users of Jenkins could benefit,
implementing this system was particularly important for CloudBees
because of how CloudBees Core on modern cloud...
Close to two years ago, we announced in
New, safer CLI in 2.54
that the traditional “Remoting” operation mode of the Jenkins command-line interface
was being deprecated for a variety of reasons, especially its very poor security record.
Today in Jenkins 2.165 support for this mode is finally being removed altogether,
in both the server and bundled jenkins-cli.jar client.
The projected June 5th LTS release will...
Oleg Nenashev and I will be speaking at DevOps World | Jenkins World in San Francisco this year about
Scaling Network Connections from the Jenkins Controller.
Over the years there have been many efforts to analyze, optimize, and fortify the “Remoting channel”
that allows a controller to orchestrate agent activity and receive build results.
Techniques such as tuning the agent launcher can improve service,
A couple of weeks ago, Tyler mentioned some
developer improvements in Essentials
that had been recently introduced:
the ability for
builds to get deployed automatically to an “Incrementals” Maven repository,
as described in
For a plugin maintainer, you just need to
turn on this support
and you are ready to both deploy individual Git commits from your repository
without the need to run heavyweight traditional Maven releases,
and to depend...
This sort of slid under the radar in the middle of some bigger changes
for the JEP-202
reference implementation, so I wanted to call it out now. Arguably this could
deserve a retroactive JEP, though I would rather fold it into a JEP for
JENKINS-49651 (see below).
As of Jenkins 2.118, or plugin parent POM 3.7, you can mark any Java member
(class, method, constructor, field,...
There is a newer version of the announcement for Jenkins administrators.
Please see this blogpost.
JEP-200 has been integrated into Jenkins weekly builds
and (if all goes well) will be a part of the next LTS line.
In a nutshell, this change is a security hardening measure
to be less permissive about deserializing Java classes defined in the Java Platform or libraries bundled with Jenkins.
Those of you updating the Pipeline Groovy plugin
to 2.3 or later will notice a change to the appearance of the configuration form.
The Snippet Generator tool is no longer a checkbox enabled inside the configuration page.
Rather, there is a link Pipeline Syntax which opens a separate page with several options.
(The link appears in the project’s sidebar; Jenkins 2 users will not...
Those of you who routinely apply all plugin updates may already have noticed that the version numbers of the plugins in the Pipeline suite have switched to a 2.x scheme. Besides aligning better with the upcoming Jenkins 2.0 core release, the plugins are now being released with independent lifecycles.
“Pipeline 1.15” (the last in the 1.x line) included simultaneous releases of...
