What happened?

When run any integration in Camel K 2.1.0 or 2.2.0-SNAPSHOT there is a warning in camel-k-operator log

"camel-k.maven.build","msg":"SLF4J: Failed to load class \"org.slf4j.impl.StaticLoggerBinder\"."}
"camel-k.maven.build","msg":"SLF4J: Defaulting to no-operation (NOP) logger implementation"}
"camel-k.maven.build","msg":"SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details."}
"camel-k.maven.build","msg":"Apache Maven 3.8.6 (84538c9988a25aec085021c365c560670ad80f63)"}

This message doesn't happen in camel-k-operator 2.0.1.

You can

Steps to reproduce

You can run just the mvn command in the camel-k-operator pod

kubectl exec -i -t `kubectl get pod -l app=camel-k -oname` -- /usr/share/maven/mvnw/mvnw --version

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
Apache Maven 3.8.6 (84538c9988a25aec085021c365c560670ad80f63)
Maven home: /usr/share/maven/wrapper/dists/apache-maven-3.8.6-bin/5f1464e3/apache-maven-3.8.6
Java version: 17.0.8.1, vendor: Eclipse Adoptium, runtime: /opt/java/openjdk
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "5.10.57", arch: "amd64", family: "unix"

The notable logback and slf4j libraries in maven are

/usr/share/maven/wrapper/dists/apache-maven-3.8.6-bin/5f1464e3/apache-maven-3.8.6/lib/jcl-over-slf4j-1.7.36.jar
/usr/share/maven/wrapper/dists/apache-maven-3.8.6-bin/5f1464e3/apache-maven-3.8.6/lib/logback-classic-1.4.8.jar
/usr/share/maven/wrapper/dists/apache-maven-3.8.6-bin/5f1464e3/apache-maven-3.8.6/lib/logback-core-1.4.8.jar
/usr/share/maven/wrapper/dists/apache-maven-3.8.6-bin/5f1464e3/apache-maven-3.8.6/lib/logstash-logback-encoder-7.3.jar
/usr/share/maven/wrapper/dists/apache-maven-3.8.6-bin/5f1464e3/apache-maven-3.8.6/lib/slf4j-api-1.7.36.jar

logback 1.4.x is incompatible to slf4j 1.7, it should use slf4j 2.0 instead.

Also, logstash-logback-encoder depends on logback 1.3.7, and maven overlays logback 1.4.8, but it seems to not be a problem.

I think this issue should not be closed as it was not fixed on camel-k.
