[jenkins] Get absolute path to workspace directory in Jenkins Pipeline plugin

I'm currently doing some evaluation on the Jenkins Pipeline plugin (formerly know as Workflow plugin). Reading the documentation I found out that I currently cannot retriev the workspace path using env.WORKSPACE:

The following variables are currently unavailable inside a workflow script:

NODE_LABELS

WORKSPACE

SCM-specific variables such as SVN_REVISION

Is there any other way how to get the absolute path to the current workspace? I need this running some test which in turn gets some parameter (absolute path to some executable file). I already tried using new File("").absolutePath() inside a @NonCPS section but looks like the non-CPS stuff gets always executed on the master.

Does anybody have a clue how to get this path without running some batch script which stores the path into some file which later on can be read in again?

For me WORKSPACE was a valid property of the pipeline itself. So when I handed over this to a Groovy method as parameter context from the pipeline script itself, I was able to access the correct value using "... ${context.WORKSPACE} ..."

(on Jenkins 2.222.3, Build Pipeline Plugin 1.5.8, Pipeline: Nodes and Processes 2.35)

Note: this solution works only if the slaves have the same directory structure as the master. pwd() will return the workspace directory on the master due to JENKINS-33511.

I used to do it using pwd() functionality of pipeline plugin. So, if you need to get a workspace on slave, you may do smth like this:

node('label'){
    //now you are on slave labeled with 'label'
    def workspace = pwd()
    //${workspace} will now contain an absolute path to job workspace on slave 
}

"WORKSPACE" environment variable works for the latest version of Jenkins Pipeline. You can use this in your Jenkins file: "${env.WORKSPACE}"

Sample use below:

def files = findFiles glob: '**/reports/*.json'
for (def i=0; i<files.length; i++) {
jsonFilePath = "${files[i].path}"       
jsonPath = "${env.WORKSPACE}" + "/" + jsonFilePath
echo jsonPath

hope that helps!!
