trigger jenkins job with file paramter - jenkins

I have a python script. I need to trigger jenkins job remotely using file parameter. That means I have a file and that file needs to be uploaded to remote Jenkins pipeline job. Please let me know if it will work or not ? Please guide.

you can add a string parameter with your file's path.
in addition, you can use "file parameter" as described in Jenkins documentation: here, and referenced in the SO question here

How to configure Jenkins "Pipeline script from SCM" with SVN

In my Jenkins project, I've configured "Pipeline script from SCM" with Subversion as the SCM, a Repository URL corresponding to a repository on our test VisualSVN server (for sake of discussion, call it https://foo.bar.com/svn/Kofax/) and a Script Path of "Jenkins files/Jenkinsfile".
When I trigger a build, I get the following console output. The repository path appears to have been improperly concatenated (e.g. it has two copies of 'svn'), but I don't know where the extraneous characters are coming from:
Started by remote host
org.tmatesoft.svn.core.SVNException: svn: E160013: '/svn/Kofax/!svn/bc/10/Jenkins%20files/Jenkinsfile' path not found: 404 Not Found (https://foo.bar.com)
I've tried removing the repository name from the Repository URL, but then Jenkins says it can't connect to the repository (as you might expect). I've also tried using an underscore rather than a space in the Script Path.
Any suggestions would be appreciated.
Unchecking the Lightweight Checkout option allowed the build to continue, so I think this might be a bug in Jenkins.
Also it appears that the repository name has to be part of the Script Path, so in my case the correct Script Path was Kofax/Jenkins_files/JenkinsFile.
Hope this helps some other Jenkins newbie.

Pass variables to jenkins from workspace

I am trying to set up builds on Jenkins. When the build is successful, I push a tag of the build using the Post build Action Git Publisher.
Until Now, these have been done manually, with the tag being given the version number, A.B.C.D (which comes from a text file). Now we are using Jenkins, D comes from the $BUILD_NUMBER Jenkins variable, but A.B.C are stored in a text file within the workspace. Is there a way I can pass A.B.C to the git publisher? or will have to do all of the git commands in a script?
Using Jenkins v1.624. Updating not currently possible (before people suggest this)
Not entirely sure if this will work the Post build Action Git Publisher (as I don't use it), and I can only test this on:
Jenkins ver. 2.32.3
EnvInject+Plugin 1.93.1
Groovy+plugin 1.30
Based on suggestion by 'Joerg S' in this post:
Creating a Jenkins environment variable using Groovy
Add a 'Execute Groovy Script' build step to read in the workspace file (tmpFile) containing A.B.C and convert it to a java based properties file - name:value) :
def custom_tag = new File('tmpfile').text.trim()
File propFile = new File('properties.text')
propFile.write "CUSTOM_TAG:"+custom_tag
Then add a 'Inject Environment Variables' build step to read in the new file, so Properties File Path is properties.text
You should then be able to use the ${CUSTOM_TAG} in your post build git publish as the TAG, as now it's an environment variable.
If this doesn't work check out the groovy code in the link above, it might offer something else.

Paramertized Build - Jenkins Pipeline

Hoping someone can point me in the right direction.
I have just started to look at the Jenkins pipeline and am trying to work out how to trigger a parameterized build for a job that already exists using the Jenkinsfile
In my Jenkinsfile i have
node {
stage 'Build My Job'
build job: 'my-build'
}
I need to be able to pass a branch name from the Jenkinsfile config to the job that is running? If i am misunderstanding anything then please let me know
Thanks
Instead of starting with a Jenkinsfile, it's easier to start with a pipeline job in which you can directly edit the pipeline script. By clicking the 'Pipeline Syntax' link you can open the snippet generator, where you can generate the Groovy for a particular step:
This Snippet Generator will help you learn the Groovy code which can be used to define various steps. Pick a step you are interested in from the list, configure it, click Generate Groovy, and you will see a Groovy statement that would call the step with that configuration. You may copy and paste the whole statement into your script, or pick up just the options you care about. (Most parameters are optional and can be omitted in your script, leaving them at default values.)
In the configuration page select 'This project is parameterized' and sleect parameter type and enter parameter name
You can access this new parameter value in you jenkinsfile using 'env.parameterName'

How to re-use groovy script in Jenkins Groovy Post Build plugin?

I have some groovy code which I am planning to re-use in Jenkins Groovy Post Build plugin of multiple jobs. How can I achieve this? Is there a place I can store the script in a global variable and call that in the jobs where ever I need?
You can load any groovy file living on the Jenkins master within the groovy postbuild and execute it. For example, you could have a special directory on the c drive where all the common scripts live. I'll update my answer later with some code that shows you how to load the script in.
Update
Assuming you have a test.groovy file on your C: drive, it should be as simple as the following in Groovy Postbuild:
evaluate(new File("C:\\test.groovy"))
Please view the comment section of the Groovy Postbuild for more examples and possibly other ways.
Here is the solution that worked for me:
Installed Scriptler plugin for Jenkins and saved the Groovy script in that. Now the script is available in JENKINS_HOME/scriptler/scripts directory. This way we can avoid manual step of copying files to Jenkins master.
Used the groovy file in Post build:
def env = manager.build.getEnvironment(manager.listener) evaluate(new File(env['JENKINS_HOME'] + "\\scriptler\\scripts\\GroovyForPostBuild.groovy"))
This is a copy of my answer to this similar question on StackOverflow:
If you wish to have the Groovy script in your Code Repository, and loaded onto the Build / Test Slave in the workspace, then you need to be aware that Groovy Postbuild runs on the Master.
For us, the master is a Unix Server, while the Build/Test Slaves are Windows PCs on the local network. As a result, prior to using the script, we must open a channel from the master to the Slave, and use a FilePath to the file.
The following worked for us:
// Get an Instance of the Build object, and from there
// the channel from the Master to the Workspace
build = Thread.currentThread().executable
channel = build.workspace.channel;
// Open a FilePath to the script
fp = new FilePath(channel, build.workspace.toString() + "<relative path to the script in Unix notation>")
// Some have suggested that the "Not NULL" check is redundant
// I've kept it for completeness
if(fp != null)
{
// 'Evaluate' requires a string, so read the file contents to a String
script = fp.readToString();
// Execute the script
evaluate(script);
}

Jenkins: Access bitbucket payload in shell

According to the documentation of the bitbucket plugin for Jenkins (https://wiki.jenkins-ci.org/display/JENKINS/BitBucket+Plugin) it should be possible to access the payload infos through the environment varaible $BITBUCKET_PAYLOAD.
However when in my build I run the command printenv, there is no environment variable called $BITBUCKET_PAYLOAD, and nothing related to it.
So it's impossible for me to access informations I need to configure my build.
You can trigger Jenkins with Generic Webhook Trigger instead.
Then you can create a variable everything having the JSONPath $. Then everything will resolve to the entire JSON payload. So you can have a shell script build step like:
echo $everything
