Hope that wasn't a direct cut-and-paste from the XML file, an
important typo in there (the double quotes to open
the "Required" property name).
Nevertheless, I think that your problem relates to your use of the
srcfiles element in the uptodate task.
As quoted in the ANT manual: "If a <srcfiles> element is used, without
also specifying a <mapper> element, the default behavior is to use a
merge mapper, with the "to" attribute set to the value of the
"targetfile" attribute." So I think your srcfiles element is
mergemapped into becoming "build.zip", not the list of files, and if
so an existing copy of a file is always considered more up to date
than a non-existent copy. Have not had a chance to cobble up a test
script, so not sure, but I would start there.

I am trying to use the uptodate task to see if I need to rebuild my

</uptodate>
<antcall target="update" />

[/code]
Based on my understanding. If the build.zip file has a last modified
date
newer then any files in the ${unzip.location}, the Required property
will be
set to true and a message will appear saying that a new build is
required.
if the unzipped location is newer then the build.zip then a message
will
appear that no new build is required. Testing this, I have tried and
older
build.zip file and a newer build.zip file. Both cases Required is
always
set, and a message appears saying a new build is required. Can
somebody help
me figure out where I am going wrong?
Thanks.
