I'd like my <tar> task to fail if the files I specify don't exist. I
currently make use of the prefix, username, group and (sometimes) mode
attributes of <tarfileset>, so I can't lose that functionality.
>From the Ant Manual, it looks like the new Resource Collection support
can handle this. But as a mere Ant user, and not Ant expert, I'm
struggling with how to reformulate my <tar> task to accomplish this. I
couldn't seem to locate any examples or tutorials for Resources. So I
thought I'd write here for help.
Here's a reduced version of the task I want to fail. If the menu.xml
file doesn't exist, I'd like the <tar> to abort:
<tar destfile="product.tar.gz" compression="gzip">
<tarfileset dir="release/prod" prefix="conf" username="admin"
group="admin">
<include name="spring/menu.xml"/>
</tarfileset>
</tar>
Normally each <tar> has multiple <tarfileset>s which in turn have
multiple <include>s.
I tried adding <restrict> and <rsel:exist> and <control> and <resource
name="*">, but Eclipse (v3.4) doesn't seem to like my syntax, as it
claims "The prefix 'rsel' for element 'rsel:exist' is not bound", which
only confuses me more. So...
1) Can I accomplish what I want to do with Resources and/or Resource
Collections? If so, how should the above be rewritten?
2) Are there other resources, ideally with examples, to help illustrate
how to use Resources and Resource Collections?
Thanks.
