Hi Kenchatty, I used QuickTimePro and iMovies here

[@gitikasurana843]

Thanks, but I have one doubt, I have to trigger a job which is currently running on different build number and build number is defined as a parameter in a downstream job.
So can you please help me on how to define the build number in the jenkinsfile ?

[@RaghavPal]

Hi Gitika,
In Jenkins, you can trigger a downstream job and pass parameters using the build step in your Jenkinsfile. The build step takes a job name and an optional map of parameters, which can include the build number.
Here is an example of how you can define the build number in your Jenkinsfile:
pipeline {
agent any
stages {
stage('Build') {
steps {
echo 'Building...'
}
}
stage('Trigger Downstream Job') {
steps {
build job: 'DownstreamJobName', parameters: [
string(name: 'BUILD_NUMBER', value: env.BUILD_NUMBER)
]
}
}
}
}
In this example, the BUILD_NUMBER parameter is passed to the downstream job and its value is set to the env.BUILD_NUMBER environment variable, which contains the current build number.
Note that the DownstreamJobName must be the name of the actual downstream job in Jenkins.
You can also pass other parameters, such as strings or booleans, to the downstream job using the parameters map.

Thanks a Lot Raghav for this session.Will the sh command in Jenkinsfile will work in windows machine eg: sh 'mvn clean install -Denv=qa'

[@RaghavPal]

on windows sh may not work

Install gitbash and you should be able to use sh

Hello Sir,
I don't know much about Jenkins, but want to learn.
I have a case when I push some file on git and this trigger Jenkins job to deploy the same file to multiple servers(windows and Linux), thus this can be achieved by Jenkins? As per understanding Jenkins is CD tools that why I think to correlate the task.

Hi sir
I need some help from you to fix my Jenkins issue.
I tried to login Jenkins with my credentials..but it is throwing 401 error.
It is showing welcome to Jenkins page. But showing invalid username and password.
It's not the issue with the credentials. Even all my team also facing the same issue.
What is the Root cause? How to fix this issue?

Hi Lakshman, to reconfigure security options in the config.xml file. Check Jenkins config.xml file which holds all the information related to the security realm and the authorization strategy
This file is located in the /var/lib/jenkins directory
One thing you must know is that, by disabling the security any anonymous user can access your Jenkins

Hello Raghav! Thanks to you I have come this far in Jenkins. I have my pipeline script which contains two stages which are build one and build two respectively. I have an active choice parameter[1] which contains a single select choice list. In build 2 I have an active choice reference parameter[2] which refers the above mentioned active choice parameter[1]. From my build one stage it generates a test.txt file. As I have mentioned in my build two active choice reference parameter[2] I want to read the above text.txt file and return the values by using split(',') or tokensize(',') as a single select parameter.
def fileContents = new File('C:/Users/Vimantha/Desktop/macAdds.properties').text.tokenize( "," )
return fileContents
I have used this inside the active choice reference parameter[2] script. But it gives me a error and doesn't execute. Can you help me with this? or is there any other way to do this?
