In my cross platform workflow build script, I am trying to iterate over
directories. I encountered some strange behavior i don't understand with
groovy and the File() object. My first attempt used File(path).eachDir
{...} it works in the Script console, but not in a job. In the job I
simply had an empty list, where running the same code in Script console
gave the expected array. Then I tried File(path).listFiles ( {} ), and
that worked on OSX in a job. Moving to linux, it failed and I had to use
'sh "ls ${path}"' and parse the output to get the strings.
If that isn't odd enough, my node() blocks are predicated on a tag, but on
my system I observe my darwin directory being listed from my linux node
job? (output below workflow script)
Anything obviously wrong? the dir listing works with the shell work
around, but the tag predicates are a bit concerning.
Jenkins 1.598
OS X 10.10.2
java version "1.8.0_31"

-- workflow script, change tag as appropriate
def linuxtag = "linux_amd64"
def darwintag = "darwin_amd64"
def getDirsSH(root) {
def dirs = []
sh "ls ${root} > clib_list.txt"
def lines = readFile('clib_list.txt').split("\r?\n")
lines.each { dirs << it }
return dirs
}
def getDirsEach(root) {
def dirs = []
new File(root).eachDir { dirs << it.name }
return dirs
}
def getDirsList(root) {
def dirs = []
new File(root).listFiles().each( { dirs << it.name })
return dirs
}
def getDirs(root, plat) {
println "-- SH ${plat} " + getDirsSH(root)
println "-- List ${plat}" + getDirsList(root)
println "-- Each ${plat}" + getDirsEach(root)
}
def platforms = [linuxtag: { node(linuxtag) { getDirs('/tmp', linuxtag)
}}, darwintag : { node(darwintag) { getDirs('/tmp', darwintag)}}]
node () {
parallel platforms
}
-- OUTPUT
-- NOTE: my darwin machine is hosting a few slaves, so /tmp/slave2 &
/tmp/slave3 directories should appear in all outputs for darwin. They
don't. Furthermore they _are_ appearing in the output of my linux tagged
jobs?
