Uptodate task not working
I am trying to use the uptodate task to see if I need to rebuild my program.
[code]
<target name="buildrequired">
<uptodate property=Required" targetfile="build.zip">
<srcfiles dir="${unzip.location}" includes="**/*" />
</uptodate>
<antcall target="update" />
<antcall target="else" />
</target>
<target name="update" if="Required">
<echo message="A new build is required." />
</target>
<target name="else" unless="Required"
<echo message="No new build is required." />
</target>
[/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.

RE: Uptodate task not working
Posted by Martin Gainty <mg...@hotmail.com>.
you need to specify a the mapper for srcfiles and specify the type for mapper
<property name="xmlBuild.notRequired" location="dest"/>
<uptodate property="xmlBuild.notRequired">
<srcfiles dir="${src}/xml" includes="**/*.dtd"/>
<mapper type="merge" to="${dest.dir}/xmlBuild.notRequired"/>
<targetfile="${deploy}\xmlClasses.jar"
</uptodate>
http://ant.apache.org/manual/CoreTasks/uptodate.html
merge type means The target file name will always be the same, as defined by
to - from will be ignored.

Re: Uptodate task not working
Posted by Faded-Maximus <fa...@gmail.com>.
Looking at the mappers that are provided: identity, flatten, glob, merge and
regexp, it seems like none of this is what I want. I looked in the ANT
section before and it doesn't seem to help unfortunately, since I still
don't get it.
I based mine off this:
[code]
<uptodate property="xmlBuild.notRequired"
targetfile="${deploy}\xmlClasses.jar" >
<srcfiles dir= "${src}/xml" includes="**/*.dtd"/>
</uptodate>
[/code]
"sets the property xmlBuild.notRequired to true if the
${deploy}/xmlClasses.jar file is more up-to-date than any of the DTD files
in the ${src}/xml directory."
To me this is almost the exact same as what I am trying to do (except for if
the zip is newer, I need to update) and they are using the default mapper
here. They have a single target file, .jar, where mine is a .zip, and a
directory of source files, which I also have.

Re: Uptodate task not working

You need to write a mapper for the srcfiles element, that will present the
files as you need them presented to the UpToDate task. What wrappers are
and what they do is something difficult to encapsulate in a single message.
I usually dislike answers that just deflect someone to another reference,
but I really do suggest that you go to Apache.org and go the ANT section, go
to the manual, and read the instructions for the UptToDate task. It contains
an explanation on how to use more than one file to compare to one file
(using the srcfiles element) and has a link to how to use mappers to create
a list of file that is in the proper format for the UpToDate task.

Thanks for the reply. I understand what you mean and it makes sense that it's
not working. I'm not sure how I would go about implementing what I actually
want too though. If the zip file is newer then any file in the unzipped
location, I want to unzip the zipped file again so I have the most uptodate
files. Do you have any ideas about how I can implement this?

Re: Uptodate task not working
Posted by Brian Stephenson <bs...@thortech-solutions.com>.
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.
