I see. I was able to do it with the find files step after installing that 
plugin. Thanks

Re: Read files from workspace in multibranch pipeline scm?

[Michael Kobit]

Your problem is the new File( piece. The pipeline code runs on a flyweight
executor on the master, and the various steps can run on allocated nodes.
You might be able to do something using FilePath
, but I think you could
use the findFiles step

which
would get you some information. You could then use the readFile step

to
get the file contents into your pipeline execution.

Read files from workspace in multibranch pipeline scm?

[anton kropp]

I'm having some issues reading files from the local workspace. As part of 
my build a set of artifact files are created and I'd like to iterate over 
them, parse their json contents, and act on it in a pipeline step. However, 
I can't seem to get reading files from the workspace to work.

My stage looks like:


stage('Push docker containers') {
def slurper = new JsonSlurper()

def files = new File(env.WORKSPACE).listFiles()

for (int i = 0; i < files.size(); i++) {
def file = files[i]
println(file.name)
if (file.name.endsWith(".json")) {
def json = slurper.parse(file)

json.each { key, value ->
// do stuff
}
}
}
}

I keep getting a null pointer on files.size. I've tried to ls the workspace 
to see whats in it, but nothing shows up.   Whats the recommended approach 
here?

Thanks
-Anton
