Hi Nick,
it's implemented and used Karaf internally.
For instance:
<feature name="webconsole" description="Base support of the Karaf
WebConsole" version="${project.version}" resolver="(obr)">
<config name="org.apache.karaf.webconsole">
realm=karaf
</config>
<feature>http</feature>
<bundle
start-level="30">mvn:org.apache.felix/org.apache.felix.metatype/${felix.metatype.version}</bundle>
<bundle
start-level="30">mvn:org.apache.karaf.webconsole/org.apache.karaf.webconsole.branding/${project.version}</bundle>
<bundle
start-level="30">mvn:org.apache.karaf.webconsole/org.apache.karaf.webconsole.console/${project.version}</bundle>
<conditional>
<condition>eventadmin</condition>
<bundle
start-level="30">mvn:org.apache.felix/org.apache.felix.webconsole.plugins.event/${felix.eventadmin.webconsole.plugin.version}</bundle>
</conditional>
<conditional>
<condition>scr</condition>
<bundle
start-level="30">mvn:org.apache.felix/org.apache.felix.webconsole.plugins.ds/${felix.scr.webconsole.plugin.version}</bundle>
</conditional>
</feature>
you can see that the webconsole ds and eventadmin plugins will be
installed only if/when the eventadmin or scr features are installed.
Regards
JB

Hey All, quick question. One of my developers is trying to use a Feature
conditional to optionally depend on another feature.
<feature name=”a”>
<conditional>
<condition>foo</condition>
<feature>b</feature>
</conditional>
I’ve told him I don’t think it was actually implemented even though it
was mentioned in the original case:
https://issues.apache.org/jira/browse/KARAF-1718 Instead, I’ve
instructed him to move the conditional down a level into “b”.
Anyone know off the top of their heads if I’m right?
Thanks,
Nick
