mvn dependency:resolve
Tree
mvn dependency:tree [-Dverbose=true]
To find out where artifacts belonging to a specific group are used, employ the following syntax:
mvn dependency:tree -Dincludes=<groupId>
mvn -s config/maven3/settings.xml dependency:tree -Dincludes=commons-beanutils
Finer granularity is possible, see Filtering the dependency tree.
Build Classpath
This is a goal that can be used to build a complete dependency classpath (less the artifact itself), as required by the Maven project artifact to function. The classpath is generated in the format to be used in java -cp. It proved useful in wrapper scripts, where it eliminates the need to manually specify the classpath.
Note that the artifact itself is not present on the classpath. If needed, it has to be added independently.
mvn dependency:build-classpath

Include Dependencies - or Some of the Dependencies - in JAR
There are situations when we want to extract some of the dependencies and bundle them with the JAR artifact. This is done using the jar plugin and the dependency plugin together, as described here:
Download Sources with the Class JAR Files
Cache Locally an Artifact Pulled from a Remote Repository
mvn dependency:get -DrepoUrl=<url> -Dartifact=<groupId>:<artifactId>:<version>
mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get -DrepoUrl=<url> -Dartifact=<groupId>:<artifactId>:<version>
mvn dependency:get -DrepoUrl=https://repo.maven.apache.org/maven2 -Dartifact=org.apache.logging.log4j:log4j-slf4j-impl:2.12.1
