I figured out that i added my logging stuff too late.: As a bundle dependency in the assembly with a startup level which is too high (30) which results in a restart of the logging system. Anyway after creating an additional feature with start level 8 and adding it to startupFeatures i am pretty close to a solution.
But i get [ERROR] Failed to execute goal org.apache.karaf.tooling:karaf-maven-plugin:4.4.6:assembly (default-assembly) on project rahla: Unable to build assembly: Unable to resolve root: missing requirement [root] osgi.identity; osgi.identity=rahla.logging; type=karaf.feature; version=1.0.16.SNAPSHOT; filter:="(&(osgi.identity=rahla.logging)(type=karaf.feature)(version>=1.0.16.SNAPSHOT))" [caused by: Unable to resolve rahla.logging/1.0.16.SNAPSHOT: missing requirement [rahla.logging/1.0.16.SNAPSHOT] osgi.identity; osgi.identity=org.agrona.core; type=osgi.bundle; version="[1.12.0,1.12.0]"; resolution:=mandatory [caused by: Unable to resolve org.agrona.core/1.12.0: missing requirement [org.agrona.core/1.12.0] osgi.wiring.package; filter:="(osgi.wiring.package=sun.nio.ch)"]] I am currently digging through the source code to see if I can change org.osgi.framework.system.packages.extra during execution of the plugin? Or does anyone know a better solution? br, Matthias On Sat, 18 May 2024 at 10:33, Matthias Leinweber <m.leinwe...@datatactics.de> wrote: > Thank you for the support.
