Hello,
I'm trying to replace the default Felix fileinstall with my custom
implementation.
To do that I built an alternative framework feature and I generated a KAR out
of it.
After that I replaced the
<dependency>
<groupId>org.apache.karaf.features</groupId>
<artifactId>framework</artifactId>
<type>kar</type>
</dependency>
dependency in my karaf assembly project with the custom KAR (this is exacltly
the same as the original one except that it contains my custom fileinstall).
Unfortunately when I try to generate the assembly I get this stacktrace:
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal
org.apache.karaf.tooling:karaf-maven-plugin:4.1.2:assembly (default-assembly)

Looking at the AssemblyMojo code, it seams that this is not the right way to
achieve what I want to do. Could you suggest the right way to replace
fileinstall with a custom implementation in my custom karaf (karaf v. 4.1.2)
assembly?
Thank you very much,
Matteo
