[FIXED] Jenkins pipeline create directory

Issue

I want to know if there is a function or pipeline plugin that allows to create directory under the workspace instead of using sh "mkdir directory"?

I've tried to use a groovy instruction new File("directory").mkdirs() but it always return an exception.

org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: Scripts not permitted to use new java.lang.RuntimeException java.lang.String

Solution

What you can do is use the dir step, if the directory doesn't exist, then the dir step will create the folders needed once you write a file or similar:

node {
    sh 'ls -l'
    dir ('foo') {
        writeFile file:'dummy', text:''
    }
    sh 'ls -l'
}

The sh steps is just there to show that the folder is created. The downside is that you will have a dummy file in the folder (the dummy write is not necessary if you're going to write other files). If I run this I get the following output:
