That would answer my question, "Is there something out there that
already does it?".
Thanks,
Shea.
Why don't you use the ivy:deliver task which has an attribute
'replacedynamicrev' for this purpose?
<ivy:deliver replacedynamicrev="true" ... />
Or am I missing something?

Maarten

Subject: possible ivy contribution: explicit dependency ivy.xml generation.
Hi folks,
I am not sure if this is the right list to post this on (but it is listed as
the Ivy development mailing list on ant.apache.org/ivy, so I'm presuming that
it is).
I have been working recently on an ant task to generate what I am referring to as
"explicit ivy.xml files". What I mean by this is that I want to generate an
ivy.xml file containing all the same configurations as the original ivy.xml file, but
which forces revisions to the exact versions that resolved at build time. This (or
something equivalent) is necessary at my company in order for us to have a reproducible
release process.
I will illustrate the problem. Suppose you have the following ivy.xml file:
<ivy-module version="2.0">
...
<dependencies>
<dependency org="A" name="name" rev="1.+" conf="default->*"/>
</dependencies>
</ivy-module>
Now, if we run a release at a given point in time, dependency A.name might resolve to "1.2". But later on, it might
resolve to "1.3" if a new version is published. This problem can be solved in several ways - you could simply have
release configurations in which you disallow the "1.+" notation, for instance, or you can just look at the generated XML
or HTML reports from <ivy: report/>, and use these to manually reconstruct a new ivy.xml file. However, I have tried to solve
the problem by writing my own ant task which looks at the ResolveReport (so it needs to be run after a call to
<ivy:report/>). This task generates a new ivy.xml file which uses the force attribute on dependencies, and sets the rev
attributes to the actual versions that got resolved, for all dependencies (including transitive ones). It also includes appropriate
"conf" attrbiutes on the dependencies. I believe this will solve the problem.
I'm just wondering: Do people think this is a good idea? Is there something out
there that already does it? I originally tried using the xsl transformations of
the ivy report XML, but that didn't work for me because it seemed to generate
one report per configuration (and I wanted one report *for all
configurations*). Anyway - if this is a useful thing, how can I go about
contributing it back to the Ivy project? Fyi, I wrote it by getting the latest
Ivy sourcecode and extending IvyPostResolveTask.
Thanks,
Mike Shea.
