The declarative Pipeline includes an implicit checkout of the repository on
each agent that will be performing a step. When you add the `node` step,
declarative Pipeline attempts to perform a checkout on that node. If you
don't need that default checkout, the `skipDefaultCheckout` option is
available.
If you need that default checkout, then you probably need to fix the file
system permissions of the /export/homes/my_user/.ssh directory so that the
user executing the Pipeline job can read the .$HOME/.ssh directory.
Command line git uses `ssh` to authenticate and clone repositories using
the secure shell protocol.
If the `/export/homes/my_user` directory is accessed over NFS, then you may
also need to assure that the agent process is not running as root. Root
access over NFS is usually not allowed.
You could check for those types of conditions in your environment with a
Jenkinsfile something like this:
pipeline {
options {
skipDefaultCheckout()
}
agent {
node {
label "!windows"
}
}
stages {
stage('Report username') {
steps {
sh 'id'
}
}
}
}
