Using Maven to compile openHAB (“mvn clean install”, to start with), I frequently see the message “SLF4J: Failed to load class “org.slf4j.impl.StaticLoggerBinder”.” in the generated output.
If you’re using Eclipse, it’s easy to add the corresponding SLF4J to the project using the "Add External JARs"option in the “Build Path” dialogue box for that particular project.
But how to do this for all projects at once when you use the Maven command line approach? Is there somewhere a global POM file that is inherited by all projects in which you can put this dependency? And if there is, how can this be done?
