Hello,
I'm trying to configure ivy/ant to unzip bundles when a new one is
downloaded. I've got:
<triggers>
<ant-call target="unzip-dependency" prefix="zip"
event="post-download-artifact" filter="type=zip AND
status=successful"/>
</triggers>
That works, when the file is downloaded the first time, but I'd like to
have a trigger that gives me a zip when it's copied from cache. Also,
since the ivy settings is shared across several projects, if
unzip-dependency doesn't exist, the build fails.
Is there a way to have the <trigger> or <ant-call> task not run if the
task doesn't exist? Or maybe fail gracefully without killing the build?
You can just define an empty unzip-dependency task. If you have a shared
build script (included in your project files with <include>), you can
can put it there, and override it as necessary in any build scripts that
do need to unzip.
Is there a way to have a trigger that fires with all the newly copied
zips (from cache, not just downloaded to cache)
You mean a post-retrieve trigger? I couldn't find such a thing.
What's the best practice on this? Am I just going about it the wrong
way?
In the absense of a post-retrieve-artifact trigger, I do it in my ant
script, and don't get ivy involved in unzipping things at all. e.g. in
shared build script:
<ivy:retrieve .../>
<antcall target="post_retrieve_dependencies"/>
///
<target name="post_retrieve_dependencies" description="override to do
any post-retrieve steps, such as unzipping dependencies"/>
Then individual build scripts that need to can override
post_resolve_dependencies to do what they want.
