For some reason I found in my lib folder the following jar log4j-1.2.14.jar. I want to exclude this jar from my final war, so I tried mvn dependency:tree but I couldn't find the parent dependency.
Also I tried to open Dependency Hierarchy from Eclipse but also I couldn't find this jar. How can I exclude this jar?
Solution
A dependency that has another dependency that has the scope provided won't lead to that provided dependency being on the classpath. It probably is there because it is needed for testing or building.
So what you should do is check your end deployment unit (your own jar/war) and check if the jar is there in the lib directory. If it is something else is managing/including that dependency. (You can use mvn dependency:tree to figure out which one).
For more information on the Maven scopes, check this. How to include a certain version of Log4j2 (when you are using it) with Spring Boot is described in this Spring.io blog-post.
