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
}
}
Had the same problem, found this solution:
The important thing here is that
createFilePath()
ins't annotated with@NonCPS
since it needs access to theenv
variable. Using@NonCPS
removes access to the "Pipeline goodness", but on the other hand it doesn't require that all local variables are serializable. You should then be able to do the search for the file inside thelistFiles()
method.
