Pipeline step having trouble resolving a file path - jenkins

Question

I am having trouble getting a shell command to complete in a stage I have defined:
stages {
stage('E2E Tests') {
steps {
node('Protractor') {
checkout scm
sh '''
npm install
sh 'protractor test/protractor.conf.js --params.underTestUrl http://192.168.132.30:8091'
'''
}
}
}
}
The shell command issues a protractor call which takes a config file argument, but this file fails to be found when protractor tries to retrieve it.
If I take a look at the workspace directory for where the repo is checked out to from the checkout scm step I can see the test directory is present with the config file present the sh step is referencing.
So I'm unsure why the file cannot be found.
I thought about trying to verify the files that can be seen around the time the protractor command is being issued.
So something like:
stages {
stage('E2E Tests') {
steps {
node('Protractor') {
checkout scm
def files = findFiles(glob: 'test/**/*.conf.js')
sh '''
npm install
sh 'protractor test/protractor.conf.js --params.underTestUrl http://192.168.132.30:8091'
'''
echo """${files[0].name} ${files[0].path} ${files[0].directory} ${files[0].length} ${files[0].lastModified}"""
}
}
}
}
But this doesnt work, I dont think findFiles can be used inside a step?
Can anyone offer any suggestions about what may be going on here?
Thanks

Answer 1

to do the debugging you were attempting (to see if the file is actually there) you could wrap the findFiles in a script (making sure your echo is before the step that fails) or use a basic find in an "sh" step like this:
stages {
stage('E2E Tests') {
steps {
node('Protractor') {
checkout scm
// you could use the unix find command instead of groovy's findFiles
sh 'find test -name *.conf.js'
// if you're using a non-dsl-step (like findFiles), you must wrap it in a script
script {
def files = findFiles(glob: 'test/**/*.conf.js')
echo """${files[0].name} ${files[0].path} ${files[0].directory} ${files[0].length} ${files[0].lastModified}"""
sh '''
npm install
sh 'protractor test/protractor.conf.js --params.underTestUrl http://192.168.132.30:8091'
'''
}
}
}
}
}
