Creating a karaf feature containing a karaf shell command breaks
karaf
Clearly this can't be true, since karaf ships with features containing bundles containing commands, but I can't get it to work.
I've created a simple karaf shell command, following the tutorial in the documentation. As per the example, it just says "hello world".
If I build that as an isolated bundle, install it into karaf and run it, it works, as per the documentation.
What I'm trying to do though is build that into a feature to include into a custom karaf distribution.
I can build the feature, and I can manually install the feature into a karaf distribution, and it works OK, I can run the resulting command.
I can build the karaf distribution containing the feature OK, but when I then run the resulting karaf then fails to initialise properly.
In the log file, I get:
Adding features:
Changes to perform:
Region: root
Bundles to install:
...
mvn:org.apache.karaf.shell/org.apache.karaf.shell.console/4.1.2
null <-- This is clearly bad
mvn:org.apache.karaf.shell/org.apache.karaf.shell.ssh/4.1.2
...
Installing bundles:
...
null <-- This is the same null as before and causes the problem below.
Error installing boot features

The console then goes funny, and you get:
Error in initialization script: etc\shell.init.script: String index out of range: 0
which I'm assuming is a knockon issue.
I've got no idea where this "null" bundle is coming from, but it's clearly causing the karaf initialisation to go wrong.
I have created an example project at https://github.com/tomq42/karaf-command-feature which I hope shows the problem.
Just build with maven, then run the karaf-distro\target\assembly\bin\karaf(.bat) command. You should see the error above on the console, and the error in the log.
Any insight would be very welcome.
Thanks.

So although moving
<feature>eventadmin</feature>
out of startupFeatures makes the command work, it seems to break a bunch of other things, so doesn't seem wise afterall. E.g, I get things like the following that only seem to happen if I've moved that line:

Hi Tom,
can you share the pom.xml you use to create your custom distro ?
It looks like some resources are missing in the distro.
