Please excuse if this a dump question but I have searched a lot and couldn't understand how to actually read Maven Dependency tee. I know this command is used to figure out the dependencies but how? This is the result of mvn dependency:tree -Dverbose in my project.

A project's dependency tree can be filtered to locate specific dependencies. For example, to find out why Velocity is being used by the Maven Dependency Plugin, we can execute the following in the project's directory: mvn dependency:tree -Dincludes=velocity:velocity.
mvn dependency:tree Command The main purpose of the dependency:tree goal is to display in form of a tree view all the dependencies of a given project. To exemplify the use of this command, we are going to use the same project created in this article: build REST API with Spring Boot.
2) Find pom. xml of your artifact. Find it using maven infrastructure. Go to https://search.maven.org/ and enter your groupId and artifactId. Or you can go to https://repo1.maven.org/maven2/ and navigate first using plugins groupId, later using artifactId and finally using its version.
It's a dependency tree. The things below a listing are dependencies of their parent.
[INFO] +- org.springframework:spring-core:jar:4.0.2.RELEASE:compile [INFO] | \- commons-logging:commons-logging:jar:1.1.3:compile Spring-core depends on commons-logging.

Jersey-common depends on rs-api and annotation-api, etc.
