Maven Dependancy Exclusion
Consider the case where you are using the Log4J2 however the dependency you are trying to add for CXF or something brings in log4j1.x. You are missing a bunch of new functionality because logger still refers to old version. Obvious you need to remove the Transitive dependency but how to identify the transitive dependencies mvn dependency:tree -Dverbose -Dincludes=log4j:log4j [groupId]:[artifactId]:[type]:[version] http://maven.apache.org/plugins/maven-dependency-plugin/examples/filtering-the-dependency-tree.html will show you the dependency-tree, but only the relevant excerpt. Using this information you can now add your exclusions to the affected pom.xml files Eg: <!-- CXF Dependancies --> < dependency > < groupId > org.apache.cxf </ groupId > < artifactId > cxf-java2wadl-plugin </ artifactId > < version > ${cxf-version} </ version > < exclusions > < exclusion >
