(Used the wrong from address in my last post attempt,
so this may get double posted - my apologies in advance
if it does)
I was looking for a Windows equiv of the chmod task
and couldn't find it. Attrib is the equivalent command,
and the company I'm with is cross platform. We use a locking
repository and check in the jars (resulting in script
failure on jar update), so I wrote an Attrib task
(a blatant rip-off of chmod). It's below, and is all
yours if you want it.
Could definitely be improved by using a common superclass
with chmod, and would be nice to also have a MakeWritable
task (or some such) that used both of these as servants.
Does not support the post-file args that attrib offers
(like /s for recursive), but could fairly easily.
<chmod file="${test.jar}" perm="uga+w"/>
<taskdef
name="attrib"
classname="org.apache.tools.ant.taskdefs.Attrib"
classpathref="ant.path"/>
<attrib file="${test.jar}" perm="-R"/>
