Can not install "Configuration as Code" plugin

[stanislr]

• Jenkins v.2.73.3
• Configuration as Code v.1.0-rc1

When trying to install plugin, we get below error(jpi file was downloaded but plugin was unable to be deployed):

Also when tried to restart Jenkins it did not start with an error:

SEVERE: Failed to initialize Jenkins hudson.util.HudsonFailedToLoad: org.jvnet.hudson.reactor.ReactorException: java.util.ConcurrentModificationException at hudson.WebAppMain$3.run(WebAppMain.java:252) Caused by: org.jvnet.hudson.reactor.ReactorException: java.util.ConcurrentModificationException at org.jvnet.hudson.reactor.Reactor.execute(Reactor.java:269) at jenkins.InitReactorRunner.run(InitReactorRunner.java:47) at jenkins.model.Jenkins.executeReactor(Jenkins.java:1124) at jenkins.model.Jenkins.(Jenkins.java:929) at hudson.model.Hudson.(Hudson.java:86) at hudson.model.Hudson.(Hudson.java:82) at hudson.WebAppMain$3.run(WebAppMain.java:235) Caused by: java.util.ConcurrentModificationException at java.util.ArrayList$Itr.checkForComodification(ArrayList.java:901) at java.util.ArrayList$Itr.next(ArrayList.java:851) at hudson.PluginManager.resolveDependantPlugins(PluginManager.java:920) at hudson.PluginManager$2$2.run(PluginManager.java:569) at org.jvnet.hudson.reactor.TaskGraphBuilder$TaskImpl.run(TaskGraphBuilder.java:169) at org.jvnet.hudson.reactor.Reactor.runTask(Reactor.java:282) at jenkins.model.Jenkins$7.runTask(Jenkins.java:1090) at org.jvnet.hudson.reactor.Reactor$2.run(Reactor.java:210) at org.jvnet.hudson.reactor.Reactor$Node.run(Reactor.java:117) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)

Do you know what may be the reason?

This is fresh install just from container? Do you make any provisioning before deployment? Your version is near 1 year old and it's not current LTS.

Could you provide a list of installed plugins with their versions? take a look https://stackoverflow.com/questions/39365417/jenkins-how-can-i-see-which-plugin-is-causing-dependency-error

[stanislr]

Hi @themysteq, No, this is not fresh install form container. This is our playground Jenkins server(not Docker container). What we have done only is:

1. Add environment variable CASC_JENKINS_CONFIG in "/etc/sysconfig/jenkins" and update "/etc/init.d/jenkins" respectively
2. Install configuration-as-code-support plugin

@stanislr the configuration-as-code plugin is not intended to be compatible with every single plugin at current stage of development. At this moment unfortunately you have to check on your own which plugin conflicts with configuration-as-code. I suppose that amd_* are your custom, in-house developed plugins. Keep in mind that "JCasC" was created to provide unattended installation and configuration. However, if it somehow works, it's not a good idea to do as you do. You should install on fresh, current Jenkins version and test which plugins are problematic (especially if you have custom, manually installed plugins). Any information about incompatibility is appreciated.

[stanislr]

Dziękuję @themysteq for replying, I already tried with fresh container installation and it worked with minimum installed plugins.

FYI after setting Active Directory and Project-based Matrix Authorization Strategy configurations yaml file generates with following error:

[themysteq]

@stanislr Glad I helped you :) Mind you close this issue and create fresh, related to ActiveDirectory plugin? I see the core of this problem probably.

[ndeloof]

active-directory plugin do declare some customDomain databound constructor parameter but no matching getter. The logic to compute this pseudo-attribute is actually hosted in the jelly view file.

afaict it is only used as a toggle for optional block, and is not even required in constructor as one can detect configured values vs null in domains parameter.

[ndeloof]

configuration-as-code should not break installation for unsupported plugins, at most it won't be able to configure them, but shouldn't prevent jenkins to load. I have no idea how it could impact jenkins boot with a ConcurrentModificationException like reported

[ewelinawilkosz]

@stanislr sorry it took so long... we've released a number of version of the plugin since you reported - 1.3 is currently latest Would it be possible for you to check and confirm if the problem still exists and this issue should be followed up?
