How do I make Jenkins 2.0 execute a sh command in the same directory as the checkout?

问题

Here's my Jenkins 2.x pipeline:

node ('master'){
    stage 'Checkout'
    checkout scm
    stage "Build Pex"
    sh('build.sh')
}

When I run this pipeline the checkout puts the code into to the workspace as expected, however instead of expecting to find the script in workspace/ (it's really there!), it looks in an unrelated directory: workspace@tmp/durable-d812f509.

Entering stage Build Pex
Proceeding
[Pipeline] sh
[workspace] Running shell script
+ build.sh
/home/conmonsysdev/deployments/jenkins_ci_2016_interns/jenkins_home/jobs/pex/branches/master/workspace@tmp/durable-d812f509/script.sh: line 2: build.sh: command not found

How do I modify this Jenkinsfile so that build.sh is executed in the exact same directory as where I checked out the project source code?

回答1:

You can enclose your actions in dir block.

checkout scm
stage "Build Pex"
dir ('your new directory') { 
    sh('build.sh')
}
...

your new directory is place holder your actual directory. By default it is a relative path to workspace. You can define absolute path, if you are sure this is present on the agent.

回答2:

The reason that your script doesn't work is because "build.sh" is not in your PATH.

The Jenkinsfile is running a "sh" script, whose entire contents is the string build.sh. The parent script is in the "@tmp" directory and will always be there - the "@tmp" directory is where Jenkins keeps the Jenkinsfile, essentially, during a run.

To fix the problem, change your line to sh "./build.sh" or sh "bash build.sh", so that the sh block in the Jenkinsfile can correctly locate the build.sh script that you want to execute.

I am having the same issue and dir is not helping, possibly because I am working inside a subdirectory of the tmp dir itself (for reason not germane here). My code looks like this

dir(srcDir){
  sh 'pwd; la -l; jenkins.sh "build.sh"'
}

(the pwd and la -l statements were added just for debugging. Issue exists w/o them.) With them I get output like:

+ pwd
/jenkins/workspace/aws-perf-test@tmp/repos/2
+ ls -l

I ultimately did this:

dir(srcDir){
  sh 'cdr=$(pwd); $cdr/jenkins.sh "build.sh"'
}

Jenkins create a folder when it make a clone from your project like this:

/var/lib/jenkins/workspace/job-name@script

For this to work you must set the file as executable if you are in a linux environment and then call the shell script.

Something like this:

// Permission to execute
sh "chmod +x -R ${env.WORKSPACE}/../${env.JOB_NAME}@script"

// Call SH
sh "${env.WORKSPACE}/../${env.JOB_NAME}@script/script.sh"
