ViewsJenkins Pipeline as Code with Docker Error
For one of my projects that I have on GitHub, I wanted to build it as a docker image and push it to my docker hub. The project is a sbt one with a Scala codebase.
Here is how my JenkinsFile is defined:
#!groovy
node {
// set this in Jenkins server under Manage Jenkins > Credentials > System > Global Credentials
docker.withRegistry('https://hub.docker.com/', 'joesan-docker-hub-credentials') {
git credentialsId: '630bd271-01e7-48c3-bc5f-5df059c1abb8', url: 'https://github.com/joesan/monix-samples.git'
sh "git rev-parse HEAD > .git/commit-id"
def commit_id = readFile('.git/commit-id').trim()
println comit_id
stage "build" {
def app = docker.build "Monix-Sample"
}
stage "publish" {
app.push 'master'
app.push "${commit_id}"
}
}
}
When I tried to run this from my Jenkins server, I get the following error:
java.io.FileNotFoundException

Since this is running inside a VM on Azure, I thought the VM was not able to reach outside, but that seems not to be the case as I was able to ssh into the VM and git pull from the Git repo. So what is the problem here? How could I make this work?

for me unchecking "lightweight checkout" fixed the issue

I experienced the exact same error. My setting:
- Pipeline build inside a dockerized Jenkins (version 2.32.3)
- In the configuration of the job, I specified a check out into a subdirectory: Open the configuration, e.g.
https://myJenkins/job/my-job/configure. At the bottom, see sectionPipeline->Additional Behaviours->Check out into a sub-directorywithLocal subdirectory for reposet to, e.g.,my-sub-dir. - Expectation: Upon check out, the
Jenkinsfileends up inmy-sub-dir/Jenkinsfile. - Via the option
Script path, you configure the location of theJenkinsfileso that Jenkins can start the build. I putmy-sub-dir/Jenkinsfileas value.
I then received the exception you pasted in your question. I fixed it by setting Script Path to Jenkinsfile. If you don't specify a sub-directory for check out, then still try double checking values for Script Path.
Note: I have another Jenkins instance at work. There I have to specify Script Path including the custom check out sub-directory (as mentioned in Expectation above).

GO TO Job-->Config-->Pipline and uncheck checkbox lightweight checkout"
lightweight checkout : selected, try to obtain the Pipeline script contents >directly from the SCM without performing a full checkout. The advantage of this mode is its efficiency; however, you will not get any changelogs or polling based on the SCM. (If you use checkout scm during the build, this will populate the changelog and initialize polling.) Also build parameters will not be substituted into SCM configuration in this mode. Only selected SCM plugins support this mode.
