      Following the examples and Youtube videos on the Jenkins shared-library wiki, I created and loaded a Global Shared Library into my project, which is using Declarative Pipelines. I know that it's working because another script call in the pipeline is already working (one that uses the SCM commands to check out my code).

      However, I'm trying to run a shell script, and the process hangs for 5 minutes, then times out. The error I see in the log is:

      [Pipeline] sh
process apparently never started in /var/jenkins_home/workspace/MY-PROJECT@tmp/durable-f178948e
(running Jenkins temporarily with -Dorg.jenkinsci.plugins.durabletask.BourneShellScript.LAUNCH_DIAGNOSTICS=true might make the problem clearer)
[Pipeline] }

      I did set the LAUNCH_DIAGNOSTICS to true, and get the following:

      sh: 1: cannot create /var/jenkins_home/workspace/MY-PROJECT@tmp/durable-404b95e3/jenkins-log.txt: Directory nonexistent
sh: 1: cannot create /var/jenkins_home/workspace/MY-PROJECT@tmp/durable-404b95e3/jenkins-result.txt.tmp: Directory nonexistent
mv: cannot stat '/var/jenkins_home/workspace/MY-PROJECT@tmp/durable-404b95e3/jenkins-result.txt.tmp': No such file or directory

      EDIT: Just to add to this, I pulled the "sh" command out of the shared library and into the pipeline. "sh" in steps hangs forever (even on just a simple "ls" command), but echo does not (e.g. echo "Hello World!" works as expected).

      Pipeline:

      @Library("jenkinsSharedLibraries@Groovy-sh-scripts") _
pipeline
{
    agent
    {
        docker 
        { 
            image 'build-image'
            args ''
        }
    }
    stages
    {
        stage('Checkout')
        {
            steps
            {
                sparseCheckoutBranch([branch: "MY-PROJECT", credentialsId: "jenkins-credentials"])
                testScript()
            }
        }
    }
}

      sparseCheckoutBranch:

      #!/usr/bin/env groovy

def call(Map params = [:])
{

  checkout([$class: 'SubversionSCM',
    additionalCredentials: [],
    excludedCommitMessages: '',
    excludedRegions: '',
    excludedRevprop: '',
    excludedUsers: '',
    filterChangelog: false,
    ignoreDirPropChanges: false,
    includedRegions: '',
    locations: [
      [
        remote: "https://myserver.com/svn/${params.branch}",
        local: "${params.branch}",
        depthOption: 'files',
        credentialsId: "${params.credentialsId}"
      ],
      [
        remote: "https://myserver.com/svn/${params.branch}/env",
        local: "${params.branch}/env",
        depthOption: 'infinity',
        credentialsId: "${params.credentialsId}"
      ]
    ],
    quietOperation: false,
    workspaceUpdater: [$class: 'UpdateWithCleanUpdater']
  ])

}

      testScript:

      #!/usr/bin/env groovy

def call()
{
  sh "echo Hello World!"
}
