How does work in feature files
Inside Karaf's "standard" feature descriptor, there is
<conditional>
<condition>webconsole</condition>
<bundle start-level="30">mvn:org.apache.karaf.webconsole/org.apache.karaf.webconsole.instance/3.0.3</bundle>
<bundle start-level="30">mvn:org.apache.karaf.webconsole/org.apache.karaf.webconsole.features/3.0.3</bundle>
<bundle start-level="30">mvn:org.apache.karaf.webconsole/org.apache.karaf.webconsole.gogo/3.0.3</bundle>
<bundle start-level="30">mvn:org.apache.karaf.webconsole/org.apache.karaf.webconsole.http/3.0.3</bundle>
</conditional>
I can't find any documentation on the <conditional> tag. Is <condition> containing a feature name?
Also I'm puzzled how this entry will affect the situation when I later on do a "feature:install webconsole".
And could these 4 bundles not just be listed as part of the "webconsole" feature description?
Thanks
- Martin

Hi Martin,
Could the info on this page https://issues.apache.org/jira/browse/KARAF-1718
help you a little bit?
Regards,
Danijel

Hi Martin,
It means that:
1/ if the webconsole feature is installed, the bundles will be installed
2/ when the webconsole feature will be installed, the bundles will be
installed
The <condition/> contains a feature name but I created Jira to enhance
it: for instance, in order to allow feature_name/version_range pattern.
Regards
JB

Thanks for the info and yes, the JIRA helped a bit :)
I ran into it while debugging an issue with the karaf-maven-plugin.
It seems to not really handle conditionals.
Eg:
<descriptors>
<descriptor>mvn:org.apache.karaf.features/spring/3.0.3/xml/features</descriptor>
<descriptor>mvn:org.apache.karaf.features/standard/3.0.3/xml/features</descriptor>
<descriptor>mvn:org.apache.karaf.features/enterprise/3.0.3/xml/features</descriptor>
</descriptors>
<features>
<feature>webconsole</feature>
...
karaf-maven-plugin does not include the bundles that are inside the "webconsole" conditional of "standard".
(For "features-add-to-repository" for example.)

Conditional means, this part is conditionally installed in case the
webconsole is already installed or in case the webconsole is just installed
those bundles are also installed. This is for better seperation of concerns
and meant as a trigger.
You'll see a lot of conditionals in the current master standard feature.
regards, Achim
P.S. in case your missing documentation, look at the jira :-)
