When we define a Jenkinsfile location in the "Pipeline script from SCM" we define the Jenkinsfile location and credetials that should be used to the SCM.
But within the Jenkins file we actually put the same url and credentialsId. Seems like code dublication. Another problem, we dont want users that editing the Jenkinsfile put any credentialsId but use the one that defined in the Jenkins job step under "SCM definitions".
Is it possible to get SCM location and credentialsId from the job?
I am getting branch and git scm location configured in the job like below
def pipelineRepoBranchName = scm.branches[0]
def pipelineRepositoryUrl = scm.userRemoteConfigs[0].url
If you dig deeper you can find the way to access credential id as well.

I will add multiple git repositories:
So I am wondering how I should set the Script Path of Jenkins?
Maybe like this: [repository url]/jenkinfile ?
I did not figure out how to run multipe repositories in pipeline. But I solved my problem by adding another JenkinsFile in the repository and set the Script Path to the new JenkinsFile (I named it as JenksFileTest).
So I have a Jenkins job wherein as part of the build.
I run one script which creates a folder in the workspace say "test"
so the script runs fine and creates the folder test.
After this, I have a maven command wherein I want to access this test folder(as an argument) I am trying it as $workspace/test
but it's not working.
Can anyone guide if i am missing anything here
Can you give us more information - maybe code snippets?
I'm not sure what you mean with 'maven command' and '$workspace/test'
If you want use a variable in a pom.xml like:
<path>${workspace}</path>
you will have to assign it in the properties:
<workspace>...location...</workspace>
Otherwise you can use maven preassigned variables like
${basedir}/
I want to trigger a Jenkins job for a maven(v3.5.3) project from my local work space folder location instead of configuring SVN Repository URL in the Source code management section. Is there a way to achieve this?. I need to test with code modifications in the project and not wanting to commit the changes, that is the purpose.
I am using Jenkins (v2.161) and it is installed in another machine.
Thanks in Advance.
Although it might look like a sort of tinkering, the source code can be pulled to the Jenknins' host from your local machine, provided that they are properly configured to communicate via ssh.
In the project build configuration on Jenkins' host:
Do not use "Source Code Management" (choose "None").
Check "Delete workspace before build starts", to avoid conflicts with previous changes.
As the very first build step, add "Execute shell" and write a few commands that pull the data, for example:
scp myusername#myhost:/path/to/myworkspace/myproject/src .
scp myusername#myhost:/path/to/myworkspace/myproject/pom.xml .
# etc for all the files/dirs you need to build the project
Then continue with the build steps that were already used for building the project from SCM.
We are just starting out using Jenkins Multi-branch pipelines. I like the idea of Jenkins automatically creating a new Jenkins job when a new branch is created. It will make sure that all releasable development is being built in Jenkins. We have about 40 or 50 projects that get branched for almost every release, and creating those 40 or so jobs every time we branch is error prone work.
However, I see there are two types of pipeline builds in Jenkins:
Regular Pipeline builds: You specify the location and branch in your Jenkins job. However, you can specify whether you want to use the script inside your Jenkins job configuration, or a script from your source repository. This would allow us to maintain a single Jenkinsfile for all of our jobs. If we change something in the build procedure, we only have to edit a single Jenkinsfile.
Multi-Branch Pipeline builds: Jenkins will automatically create a new Jenkins job for you when a new branch is created. This means we no longer have to create dozens of new Jenkins projects when a new branch occurs. However, it looks like the Jenkinsfile must be located on the root of the project. If you make a basic change in your build procedure, you have to update all Jenkins projects.
I'd like to be able to use the Multi-branch Pipeline build, but I want to either specify where to pull up the Jenkinsfile from our repository, or include a master Jenkinsfile from a repository URL.
Is there a way to do this with Jenkins Multi-branch pipelines?
If you have common build logic across repos, you can move most of the pipeline logic to a separate groovy script. This script can then be referenced in any Jenkinsfile.
This could be done either by checking another checkout of the repo that the the groovy script is in to another directory and then doing a standard groovy load or, probably the better approach would be by storing it as a groovy script in the Jenkins Global Script Library - which is essentially a self-contained git repo within Jenkins
(see https://github.com/jenkinsci/workflow-cps-global-lib-plugin/blob/master/README.md for more details).
We had a similar requirement, and created a global groovy method in a script that was maintained in Git and deployed to Jenkins' Global script library under /vars/ when it changed:
e.g. the script 'scriptName.groovy' has
def someMethod(){
//some build logic
stage 'Some Stage'
node(){
//do something
}
}
That way the common function could be called in any Jenkinsfile via
scriptName.methodName()
I'm sure I'm doing something stupid that most of you are going to laugh at, but I can't seem to get Jenkins to build with multi-branch pipeline. I've simplified the problem down to the very essence. A single branch (master) with an empty node JenkinsFile. I have a second project, a standard Freestyle project that basically runs true to verify it builds.
Here's my Freestyle configuration:
Repository URL: ssh://git#rgit.vegicorp.net:7999/dw/foobar.git
Credentials: None
BUILD
Execute Shell
Command: True
And the build works. (Basically, the repo checks out, true runs, and the build is reported as a success.
Here's my Multibranch build configuration:
BRANCH SOURCES
Project Repository: ssh://git#rgit.vegicorp.net:7999/dw/foobar.git
Credentials: None
BUILD CONFIGURATION
Mode: By JenkinsFile
When I do Branch Indexing, I get a failure and the log says:
Started
Setting origin to ssh://git#cmstash.travelclick.net:7999/dw/foobar.git

My JenkinsFile (which sits in the root of the Repo) says:
node {
}
This works when I am not doing a multi-branch pipeline and just put this in as a Jenkins build script. I just want to verify that Jenkins is able to pick up my JenkinsFile.
Found the issue: You must have credentials set even if you don't need to use credentials. The freestyle job has no credentials set and has access to this particular Git repository. In our old Jenkins server, we use ssh:// and setup public/private keys in the $HOME/.ssh directory for our Git projects. None of our Git projects use credentials and don't need them.
However, Multibranch Pipeline does require credentials -- and a non-null JenkinsFile. When I finally set the credential, the job I had to add at least one step in the JenkinsFile or else it wouldn't trigger a single build.)
i think you are also hitting BUG like me ..

Did you got this resolved ?
