Using FilePath to access workspace on slave in Jenkins pipeline

[Harsha Adiga]

I need to check for the existence of a certain .exe file in my workspace as part of my pipeline build job. I tried to use the below Groovy script from my Jenkinsfile to do the same. But I think the File class by default tries to look for the workspace directory on jenkins master and fails.

@com.cloudbees.groovy.cps.NonCPS

def checkJacoco(isJacocoEnabled) {

new File(pwd()).eachFileRecurse(FILES) { it ->

if (it.name == 'jacoco.exec' || it.name == 'Jacoco.exec') 

isJacocoEnabled = true

}

}

How to access the file system on slave using Groovy from inside the Jenkinsfile? 

I also tried the below code. But I am getting No such property: build for class: groovy.lang.Binding error.  I also tried to use the manager object instead. But get the same error.

@com.cloudbees.groovy.cps.NonCPS

def checkJacoco(isJacocoEnabled) {

channel = build.workspace.channel 

rootDirRemote = new FilePath(channel, pwd()) 

println "rootDirRemote::$rootDirRemote" 

rootDirRemote.eachFileRecurse(FILES) { it -> 

if (it.name == 'jacoco.exec' || it.name == 'Jacoco.exec') { 

println "Jacoco Exists:: ${it.path}" 

isJacocoEnabled = true 

} 

}

Hi,


have you tired the findFiles step?

Hi Christoph,

It worked. I was not aware of this utility apis since I had not installed the pipeline utility plugin on my jenkins. I think it would be nice if this plugin gets included by default  when we install the pipeline plugin. Thanks for your help.

Regards,

Harsha

I am also facing the same issue, using `findFiles` does not solve the problem as it only searches for the file in the current directory and does not search for it recursively inside other directories. I have posted the same question on stackoverflow https://stackoverflow.com/questions/41720831/unable-to-recognize-workspace-as-directory-using-jenkinsfile-pipline-plugin, any help is greatly appreciated.
