Listing files in workspace

Is it possible to list the files in the current workspace?

I can see the streamFileFromWorkspace() and readFileFromWorkspace() methods but I would like to find out the file names before reading them.

I guess that I can use the WORKSPACE variable in conjunction with the eachFile() and eachDir() methods but I was wondering if there was already something better.

There are no convenience methods for listing files. Using the WORKSPACE variable will only work when your seed job runs on the Jenkins master. Otherwise you will have to use the Jenkins API to access the files on a build node.

Thanks for the information.

Thankfully I am working on the master.
I have never worked with slave/build nodes but I may do in the future so I guess that I should look at how to do this properly.
I have looked at some of the code in the plugin and it is not obvious to me how I should go about accessing the Jenkins API for the job so that I can retrieve files from the master.
Can you give me a hint?

With much investigation I have found that I can do the following...

this.jm.build.getWorkspace().list() .each { FilePath fp ->
println("Found file ${fp.name}")
}

I found the jm.build bit by reading the plugin sources and I would like to know how safe this is in terms of future-proofness of the plugin?
I.e... are the "jm" property if the JobParent class and the "build" property of the JenkinsJobManagement class likely to change?

Hm, that a hidden feature, which could change in the future. I would rely on the Jenkins API, which is unlikely to change anytime soon.

hudson.FilePath workspace = hudson.model.Executor.currentExecutor().getCurrentWorkspace()

I wondered whether you might say that... that's why I asked.
(And I was so pleased to find such a simple method of finding it!)

Thanks for the hint... It's working just fine.
