Re: Using @grab to fetch SNAPSHOT jar in groovy sometimes can't be recoganized correctly if updating the SNAPSHOT

[pan]

Updates:

It might not be a good idea to use @grab in Jenkins pipeline script.

We also found an issue about this: 
https://issues.jenkins-ci.org/browse/JENKINS-48974, this will cause the 
parallel jobs which @grab the same direct/indirect dependencies failed.

It seems related to the groovy/ivy issue: 
https://issues.apache.org/jira/browse/GROOVY-7407. And it’s not fixed yet…
We also consider the way of @Library, but in the groovy lib, we still need 
@grab 3rd party lib, which is the same situation.

Anyway, we refactor the dependencies into a service and call rest api from 
the pipeline script, it seems working.

Re: Jenkins to run selenium scripts

[Jan Monterrubio]

Yes, you can probably add the windows machine as an agent and have it
configured to build jobs with a label WINDOWS. Jenkins will ssh or rdp to
the node for you

Jenkins to run selenium scripts

[maninadh golla]

Hello All,


My team have asked me to integrate selenium scripts with jenkins. There is 
a dedicated windows server which QA team is using to run selenium scripts. 
So i am just wondering if there is a way to log into that windows machine 
and run the scripts through Jenkins.


Your reply will be highly appriciated.

Thanks,
Mani.

Re: Help: Jenkins builds ONLY on master OR slave

[Ivan Fernandez Calvo]

You can make it with a pipeline with 2 stages in parallel with the same steps 
and different nodes somethinlike this


pipeline{

stages {
  stage(‘parallel’) {
parallel {
  stage(‘master’){
agent { label ‘master’}
steps{
  //steps
}
  }
  stage(‘agent’){
agent { label ‘agent’ }
steps {
  //steps
}
  }
}
}

}

On steps you could use the build step, it launch a job, or translate your job 
to pipeline

What’s the .pkg.pkg for?

Usually I’ve seen the import as:

When the job builds on the slave agent, does it not build concurrently with

Alternative to specifying branch/tag/version in library identifier

[afeller]

Up to now, I've followed the documentation of specifying the 
branch/tag/version to checkout from Git for shared library using identifer: 
'thing@version' 

 approach, however I suspect this causes issues when referring to the 
library using library('thing').pkg.pkg... as it doesn't recognize it.

Is there another way to configure the version to checkout?

Re: Pod still released after "Pod Retention" set to "On Failure" for Kubernetes Plugin

When you say "pod still released" what do you mean? the retention means the
pod will not be deleted in k8s but not used by jenkins

Pod still released after "Pod Retention" set to "On Failure" for Kubernetes Plugin

[Evan]

 

Jenkins 2.138.2

Kubernetes Plugin 1.13.2

 

When using kubernetes plugin to dynamically provision Jenkins slave, the 
needs now is to reserve workspace of Jenkins slave when the job failed, 
"Pod Retention" seems to be useful.

 

When "Pod Retention" is set to "Always", after job finished, the pod is 
reserved;


But when "Pod Retention" set to "On Failure", after job fails, the pod 
still released.


Is it a bug of plugin or my setting problem?

Help: Jenkins builds ONLY on master OR slave

[firstrose]

Hi

I got two machines with Win10. One is jenkins' master and the other is 
slave. Both are shown as online in dashboard.

Both node are configured as 'Use this node as much as possible'.

My Project is configured as 'Execute concurrent builds if necessary'.

I want to build the project on master AND slave concurrently, but found 
jenkins only start build action on slave. Only after mark slave as offline, 
master would take build action.

I tried label them but failed.

Master has 2 executors while slave has one, but they are the default 
setting value.

Jenkins version : 2.138.2

Is there any thing I missed?

Thanks.
