Dirk Heinrichs updated GROOVY-8341:
-----------------------------------
Description:
The documentation for those two methods states: "Sub-directories are
recursively searched in a depth-first fashion." But the result is NOT
depth-first, as the following example shows:
Given a directory tree of {code}/tmp
|-/foo
| |-/bar
| |-/foo
| |-/bar
| |-/baz
|-/baz{code}
the following simple code {code}#!/usr/bin/groovy
File rootDir = new File(new URI('file:/tmp/foo'))
rootDir.eachDirRecurse {
println(it)
}{code}
gives this result {code}/tmp/foo/bar
/tmp/foo/bar/baz
/tmp/foo/bar/foo
/tmp/foo/bar/bar
/tmp/foo/baz{code}
while {code}% find /tmp/foo -depth -type d{code}
correctly gives {code}/tmp/foo/bar/baz
/tmp/foo/bar/foo
/tmp/foo/bar/bar
/tmp/foo/bar
/tmp/foo/baz
/tmp/foo{code}
