Selecting optional dependencies of OSGi-bundles with Ivy (+150 bounty on StackOverflow)
Hello,
I posted a question about selecting optional dependencies of OSGI-bundle on Stackoverflow:
ant - Selecting optional dependencies of OSGi-bundles with Ivy - Stack Overflow
ant - Selecting optional dependencies of OSGi-bundles with Ivy - Stack Overflow
I use Ivy to resolve OSGi bundles, like org.eclipse.jdt: <dependencies> <dependency org="bundle" name="org.eclipse.jdt" rev="x.y.z"/>
</dependencies>
View on stackoverflow.com Preview by Yahoo
Even issuing a bounty of +150 didn't helped... No answers, no comments. (The bounty expired within 24 hours.)
I going to repost my question here hoping to get an answer and also hoping to give away +150 reputation on StackOverflow.
I use Ivy to resolve OSGi bundles, like org.eclipse.jdt:
<dependencies><dependencyorg="bundle"name="org.eclipse.jdt"rev="x.y.z"/></dependencies>
It works fine and gives me all mandatory dependencies.
My question is, how can I select some (not all) optional dependencies of transitive bundles?
I can:
* Select optional dependencies of org.eclipse.jdt by activating use_xxx configuration
* Select all optional dependencies using transitive-optional configuration
What I actually need is a possibility to globally activate a configuration use_yyy. Globally means (applying to all transitive dependencies):
* If a module doesn't have this configuration, do nothing
* If a module does have this configuration, activate it
Thank you very much for help!
Kind regards,
Boris Brodski

Maybe you can use this trick: you can specify a range of versions, a range so wide that it will match anything existing; you can write rev="[0,)"

Hello Nicolas,

this is exactly, what I need. But unfortunately the "rev" attribute is mandatory:
<dependency org="bundle" name="org.eclipse.xtend.core" conf="default->default,use_org.eclipse.jdt.core"/>
produces
[xml parsing: ... cvc-complex-type.4: Attribute 'rev' must appear on element 'dependency' ...]
Do you have an Idea, how can I activate this configuration without specifying the version of the bundle explicitly?
Thank you!
Cheers,
Boris

Yes you can, just like a normal ivy file:
<dependency org="bundle" name="org.eclipse.jdt" conf="default->use_xyz" />
But this "use_xyz" configuration will be the one of org.eclipse.jdt, not one of its dependency.

Yes you can, just like a normal ivy file:
<dependency org="bundle" name="org.eclipse.jdt" conf="default->use_xyz" />
But this "use_xyz" configuration will be the one of org.eclipse.jdt, not one of its dependency.

Hello Nicolas,
thank you for the quick reply. I use your suggestion already, but specifying the version is some kind nasty, especially if you have many such optional dependencies.
Is there really absolutely no possibility to just activate a configuration of a bundle, like
<dependency org="bundle" name="org.eclipse.jdt"> <!-- No version here -->
<conf name="use_xyz"/>
</dependency>
This would be completely enough for me!
Cheers,
Boris

But if in your use case you need an optional dependency to be fetched, then it is actually required for you. So in your ivy.xml, put an extra line about the dependency you require.
The non ideal point here is about choosing the right version of your dependency. With a pure OSGi resolver, you just declare a dependency on a bundle symbolic name, OSGi will figure out the version which can match while looking up the optional dependencies. Ivy cannot do that, there is no notion of optionality, either the configuration is in the dependency graph, either it's not. So you'll have to put a version to the extra dependency.
