Thanks! Not working, though. Getting:
No such property: compareVersions for class: Sorters
with:
class Sorters {
def compareVersions = { afile, bfile ->
return getVersion(afile).toInteger() <=> getVersion(bfile).toInteger()
}
}
and called with:
res.sort(Sorters.compareVersions)
Any thoughts are appreciated! Thanks!!
