Erreur: "Arguments nommés attendus" en parallèle dans le script groovy Jenkins

J'ai un pipeline Jenkins 2.0, avec un groovyscript comme celui-ci:

node('nnh561.raijin') {
    stage 'checkout'
    build('trunk/checkout')

    stage 'build'
    parallel(
        { build('trunk/build/gfortran') },
        { build('trunk/build/ifort') }
    )

}

Chacun des travaux individuels se déroule correctement, mais lorsque j'essaie d'exécuter le pipeline, il crache cette erreur lorsqu'il atteint l'étape parallèle:

Des idées ce qui pourrait causer quelque chose comme ça?

Ahh ... le pipeline a besoin d'une carte, pas d'une liste. Nommer les arguments fonctionne:

node('nnh561.raijin') {
    stage 'checkout'{
    build('trunk/checkout')}

    stage 'build'
    parallel (
        'gfortran': { build('trunk/build/gfortran') },
        'ifort': { build('trunk/build/ifort') }
    )
}
