I'm trying to get JSON format logging enabled in Karaf. Trying to do something similar to what's described in https://ops4j1.jira.com/browse/PAXLOGGING-168
On a fresh copy of Karaf 4.2.5 I've added to /etc/startup.properties: mvn\:com.fasterxml.jackson.core/jackson-core/2.9.5 = 8 mvn\:com.fasterxml.jackson.core/jackson-annotations/2.9.5 = 8 mvn\:com.fasterxml.jackson.core/jackson-databind/2.9.5 = 8 mvn\:ch.qos.logback/logback-classic/1.2.2 = 8 mvn\:ch.qos.logback/logback-core/1.2.2 = 8 mvn\:ch.qos.logback.contrib/logback-json-core/0.1.5 = 8 mvn\:ch.qos.logback.contrib/logback-json-classic/0.1.5 = 8 mvn\:org.ops4j.pax.logging/pax-logging-logback/1.10.1 = 8 The above jars have been added to the system folder. They look like: logback: https://pastebin.com/raw/60Pnu8f1 jackson: https://pastebin.com/raw/NkUqZrGS My etc/org.ops4j.pax.logging.cfg contains the line: org.ops4j.pax.logging.logback.config.file=${karaf.base}/etc/logback.xml The log back is the same one from https://ops4j1.jira.com/browse/PAXLOGGING-168 When I startup Karaf I get the following CNF error related to Jackson. Shouldn't the startup.properties file make those classes available? WARN in ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP@5c3aaee6 - SizeAndTimeBasedFNATP is deprecated.
