Looking to this example and trying it in my case I think I understand
what is going wrong.
If I run the commands you show, I get:
g! ((bundle 0) adapt ((bundle 0) loadClass
org.osgi.framework.wiring.FrameworkWiring)) getDependencyClosure [
(bundle 9) ]
9|Resolved | 1|mybundle_symboicname (1.0.0)
g! inspect c *package 9
mybundle_symboicname[9] provides:
-------------------------------------------
*package [EMPTY]
If I understand correctly this output, It is what I'd have expected
since myBundle doesn't have any capability.
The thing is that I would expect that the Dependency Closure would also
contain the bundles related to myBundle's requirements. I think I may
misunderstood the documentation:
...The graph is expanded by adding any bundle that is either wired to a
package that is currently exported by a bundle in the graph or
__requires a bundle in the graph__...
From that last part I thought that the bundles wired to myBundle by its
requirements would also be in the dependency closure.
If that is not the case, is there a way to get the bundles wired to
myBundle by its requirements (and the requirements of those bundles, and
so on...)?
Thank you again for your help
Kind regards

This looks correct, but there could always be bugs, I guess.

Hi everybody,
I'm trying to get a bundle's dependency closure by using the method
getDependencyClosure. However if I do sth like:
context.getBundle(0).adapt(FrameworkWiring.class).getDependencyClosure(Arrays.asList(myBundle));
to get myBundle's closure, all this call is returning is the bundle
(myBundle) itself.
From getDependencyClosure javadoc:
/Returns the dependency closure for the specified bundles.
A graph of bundles is computed starting with the specified bundles.
The graph is expanded by adding any bundle that is either wired to a
package that is currently exported by a bundle in the graph or
requires a bundle in the graph. The graph is fully constructed when
there is no bundle outside the graph that is wired to a bundle in the
graph. The graph may contain UNINSTALLED bundles that are removal
pending./
I understand that the result of the previously cited call should be
all the bundles wired (by a requirement or a capability) to myBundle.
What am I doing wrong?
And I would like to ask you also if there is a way of getting only
the closure formed by the bundles wired to myBundle by its
requirements (i.e. only get those bundles that are needed to resolve
myBundle).
Thanks in advance for any help you can kindly give me
Kind regards
