I am a newbie to the jenkins and trying to run a windows batch job in Jenkins slave. I can see the workspace with all the svn code in job but when am trying to access the command from the workspace folder , i am getting an error path not specified. this is because the Jenkins master is having workspace path as [workspace]/[jobname] where as in slave it is [jobname]/[workspace]. How can i identify the workspace path in jenkins master and run from the slave . please help!
Your not supposed to work on the master. You need to tell which slave your working on with the agent{ label 's1'} block. After, go see the Snippet Generator and check the Checkout function for your svn request.

I am trying to run a pipeline job that get its' pipeline file from TFS but the mapping of the workspace and the checkout is done on the Master instead of the Slave.
I have Jenkins-master which is installed on a linux machine and I connected a windows machine as a slave to it. I created a pipeline job with 'Pipeline script from SCM' option selected for TFS.
How can I make the windows slave run that pipeline job?
The master can't run that job because it is running on linux and it fails when it is trying to map a workspace to TFS in order to download the pipeline script and run it.
Even if I create another pipeline job and select to hard-code a script to run my original pipeline job like this:
node('WIN_SLAVE') {
build job: 'My_Pipeline'
}
It doesn't work.
And I can see in the output that the initiali script (above) is in fact running on my windows slave, but when it's building the job 'My_Pipeline' it still tries to map a workspace to the Jenkins-master at it's linux machine path /var/jenkins/... and it fails.
If the initial pipeline script ran at the windows slave, why does the other pipeline script not running on the same node? Why is it trying again to checkout the pipeline file from TFS to the Jenkins-Master?
How can I make the windows slave checkout the pipeline file and run it?
Here are some things to check...
Make sure you disabled the original job, or you are completely redefining it for running on the slave, because you indicated you set up “another job” for the slave. It appears that this other job is just triggering the previous job, rather than defining its own specifications. When the job is ran on the slave, it’s just running whatever settings are in that original job.
Also, If you have the box checked to build when a change is pushed to TFS, then your original job could still be trying to run every time a change is made to TFS.
Verify the slaves Remote root directory is set properly in the slave configuration under Manage Jenkins -> Manage Nodes.
Since this slave job is triggering the other job you originally created on the master, then it will build on the master as expected.
Instead of referencing the My_Pipeline job, change the My_Pipeline job itself to run on the slave. If you are using a declarative Pipeline for the original job, then change that original job to run on the slave within the original job settings. You can do it similarly to how you have indicated above, just define the node in the original job.
If the original job is a freestyle project, there is a checkbox titled Restrict where this project can be run. Check that and include the name of the slave in the Label Expression. When you run the job, it will then be restricted to the slave.
Lastly, posting the My_Pipeline job will be helpful.
We're running tests and producing build files on a jenkins master and a jenkins slave for extra parallellisation, our RCPTT tests takes ages.
Our problem is that Jenkins -> -> Show workspace only shows the workspace on the master, so we have no way to get the builds except copying files manually over ssh.
We don't want duplication since different patches run either on master or slave, and we want to be able to get the files from both master and slave nodes.
You can use "Copy To Slave Plugin" to copy any files from master to slave.
If you use the Jenkins pipeline plugin https://jenkins.io/doc/book/pipeline/
then you can use stash / unstash:

Can someone direct me here? I have a simple job configured in Jenkins on a WINDOWS environment (master and all slaves running on windows) and the job is supposed to run on a particular slave. When you build the job, the build log ( log.log) gets stored in ” %JENKINS_HOME%\jobs\\builds\%BUILD_NUMBER%\” on the master.
I do have a Jenkins workspace (which is required when you add a slave node) set on the slave for this job–where nothing gets stored when the job runs.
With this scenario, I would like to copy the build log (log.log file that’s available on the master) to a share drive. Please advise me the way to get this done. I have tried few plugins “Copy to slave”, “Copy Artifact Plugin” and ArtifactDeployer Plugin…I could not get them working to meet what I need.
Use a second build action with the execute batch option. Put the copy command there to copy the log to another location.
The following command kind-of works:
curl ${BUILD_URL}consoleFull -o ${TargetDir}/Log.txt
where
TargetDir="${WORKSPACE}/Directory/target"
BUILD_URL and WORKSPACE are set by Jenkins. Unfortunately Jenkins doesn't copy the whole log. I've tried consoleText and gotten the same result: partial logs files. :-(
I have just added a slave to my Jenkins build - with the idea that I can now deploy artefacts to either my dev server or my test server.
However i've now hit a problem.
When I deploy a job on the master slave, the job build directory is
$JENKINS_HOME/localmoduledirectory (as defined in the build job)
However when I deploy my job via the slave the build directory is different which breaks my jobs. The build directory is
$JENKINS_HOME/workspace/build job title/localmoduledirectory
I know I can change the workspace root directory location for the master under configure settings /advances .. so can change it to $JENKINS_HOME/workspace, but I want to stop the slave using the build job title in the path.
The end result I'm after is to have jenkins, building / deploying from the same location on two servers i.e /opt/jenkins/workspace/localmoduledirectory.
Any ideas ?
ok after lots of head scratching ...
managed to discover that the mvn plugin has a custom workspace option hidden under advanced. so configured all jobs with a customer workspace of /opt/jenkins.
I have created a Jenkins job which used to run in the master and I have the build.xml file in the master.
Now I have added a slave node and added the setting Restrict where this project can be run so that my job always runs on a particular slave.
Now my build jobs are failing and I can see:
[EnvInject] - Loading node environment variables.
Building remotely on demo_slave_inst2 (slave1) in workspace /root/slave/workspace/demo_job
FATAL: Unable to find build script at /root/slave/workspace/demo_job/autobvt.xml
Build step 'Invoke Ant' marked build as failure
Recording test results
Finished: FAILURE
This autobvt.xml file already exists in the master. So looks like I need to copy this file over to the slave node manually which does not looks like quite handy.
How I can instruct jenkins to copy this as part of the build?
Use "Copy data to Workspace" http://wiki.jenkins-ci.org/display/JENKINS/Copy+Data+To+Workspace+Plugin using which you can copy the files from master to slave and run them as a part of build process (No manual effort needed!)
I sorted the issue using the Copy to Slave plugin.
