new File is adding C: to the path of a linux container

[red 888]

I have a windows master that executes a stage in a container on a linux slave.

Groovy is appending a "C:" to the path inside the linux container- totally breaking it:

stage('sdlfkjsldkf') {
    agent {
        docker {
            image "library/alpine"
        }
    }

    steps {
        script {
            new File("${workspace}/blah")
                .traverse(type: FileType.DIRECTORIES, nameFilter: 'subfolder') {
                echo "${it.path}"
            }
        }

The error I get:

java.io.FileNotFoundException: C:\home\jenkins\workspace\myworkspace\blah\subfolder

if I echo ${workspace} it correctly starts at /home, but it looks like new file want to add "C:" to the beginning of it

Also, depending on what your goals are in the future, you may want to use the findFiles which is part of the pipeline utility steps plugin.

For example, I use the following to find a string in the log files of some test run and fail the pipeline if it finds it using findFiles:

   

def files = findFiles(glob: 'FEATURE_VALIDATION/smoketest/*.log');
for (def file : files) {
    def logFile = readFile encoding: 'UTF-8', file: "${file.path}";
    if (logFile.contains("FAIL***")) {
        currentBuild.result = "FAILURE";
        break;
    }
}

Hello,

I think the problem that you are experiencing can be explained here. 

Basically, you can't use new File to create files in the slaves workspace (using the new File call will only do file things on the master).  To do file interactions in the slaves workspace you'll have to use the FilePath.

Files generated by jenkins during a build is created in the master. You have to use the "readFile" to use it in the compute environment of the slaves/agents

This makes sense to me now. I'm trying to execute groovy code inside the slave (duh that obviously won't work). The groovy runtime is one the master so thats why its giving me back windows file paths- right?
