Jenkins Groovy with Java Stream API

[Sverre Moe-2]

The following piece of code works fine in Groovy, but Jenkins complains about unexpected token: ->

    final def files = findFiles(glob: filePattern)

    final def rootNode = files.stream()

        .map(file -> findByContent(file.getPath()))

        .filter(node -> node != null)

        .findFirst()

To get this working in a local Groovy script the findFile is switched with a simple List of strings.

So why is it not working in Jenkins?

Here is a solution that does work in both Groovy and Jenkins

    def foundRootNode = null

    for(file in files) {

        final def rootNode = findByContent(file.getPath());

        if (rootNode != null) {

            foundRootNode = rootNode

            break;

        }

    }

However it is not as elegant as using Java Stream API.
