Answer 1

When running Groovy in the context of Jenkins pipeline job the above answers do not work (at least on version 2.60.2), but the following does:

node {
    obj = ret2()
    fw = obj[0]
    lw = obj[1]
    echo "fw=${fw}"
    echo "lw=${lw}"
}

def ret2()
{
    return [5, 7]
}

Or alternatively:

node {
    obj = ret2()
    fw = obj.a
    lw = obj.b
    echo "fw=${fw}"
    echo "lw=${lw}"
}

def ret2()
{
    return [a:5, b:7]
}
