How to check if directory exists outside of workspace from a jenkins pipeline script

Question

Given I have a directory path, how do I check if this directory exists outside of the workspace from a jenkins pipeline script.

Answer 1

Tried a few things and turned out the answer was already in front of me. fileExists can check for directories as well. Here's how I got around the problem. In this example, I am creating a directory on Windows if it doesn't exist.

Step 1: dir into the directory

dir("C:/_Tests")

Step 2: Now, use fileExists without any file name.

if(!fileExists("/"))
{
  bat "mkdir \"C:/_Tests\""
}

Answer 2

fileExists(target_dir) in pipeline checks the given file in workspace, it is not permitted to access the outside.

to do this, the sh or bat in pipeline can help verify if the target directory exists by calling shell command.

res = sh(script: "test -d ${target_dir} && echo '1' || echo '0' ", returnStdout: true).trim()
if(res=='1'){
    echo 'yes'
} else {
    echo 'no'
}

Answer 3

im not sure that that was your question but fileExists() works for directories as well

Answer 4

for anyone interested a bit more universal (windows, mac, linux and shared library...):

def listDirectories(String Directory, String Pattern) {
  def dlist = []
  new File(Directory).eachDir {dlist << it.name }
  dlist.sort()
  dlist = dlist.findAll { it.contains Pattern }

  return dlist
}

usage (for this):

if (listDirectories(Directory: "C:/", Pattern: "Windows").size() == 1) { ... }

Answer 5

None from suggestions above worked for me...

This is 100% working code:

                        efs_path = '~/efs-mount-point'
                        stdout = sh( script: '''#!/bin/bash
                        set -ex
                        if [ -d ''' + efs_path + ''' ]; then
                            echo "true"
                        else
                            echo "false"
                        fi
                        ''', returnStdout: true)

                        echo stdout

                        if (stdout.contains('false')) {
                            error('No such directory: ' + efs_path)
                        }
