Name: Apache Maven Dependency Plugin

Description: The Apache Maven Dependency plugin provides goals to manage dependencies.
It provides utility goals to work with dependencies like copying, unpacking, analyzing, resolving and many more.

Plugin coordinates:
Group Id: org.apache.maven.plugins
Artifact Id: maven-dependency-plugin
Version: 3.1.1

Goal Prefix: dependency

The goal help:help gives general information about the dependency plugin and lists its goals:
$ mvn dependency:help $ mvn dependency:help -Ddetail=true -Dgoal=analyze
The goal help:describe gives detailed information about the dependency and lists its goals:
$ mvn help:describe -Dplugin="org.apache.maven.plugins:maven-dependency-plugin" $ mvn help:describe -Dplugin="org.apache.maven.plugins:maven-dependency-plugin" -Ddetail=true -Dgoal=analyze
The dependency plugin has the following goals:

• help: Displays help information on maven-dependency-plugin. Call mvn dependency:help -Ddetail=true -Dgoal=<goal-name> to display parameter details.
  
  
• analyze: Analyzes the dependencies of this project and determines which are: used and declared; used and undeclared; unused and declared.
  
  
• analyze-dep-mgt: This mojo looks at the dependencies after final resolution and looks for mismatches in your dependencyManagement section.
  
  
• analyze-duplicate: Analyzes the <dependencies/> and <dependencyManagement/> tags in the pom.xml and determines the duplicate declared dependencies.
  
  
• analyze-only: Analyzes the dependencies of this project and determines which are: used and declared; used and undeclared; unused and declared.
  
  
• analyze-report: Analyzes the dependencies of this project and produces a report that summarizes which are: used and declared; used and undeclared; unused and declared.
  
  
• resolve: Goal that resolves the project dependencies from the repository.
  
  
• resolve-plugins: Goal that resolves all project plugins and reports and their dependencies.
  
  
• tree: Displays the dependency tree for this project.
  
  
• list: Displays the list of dependencies for this project.
  
  
• list-repositories: Goal that resolves all project dependencies and then lists the repositories used by the build and by the transitive dependencies.
  
  
• display-ancestors: Displays all ancestor POMs of the project.
  
  
• sources: Goal that resolves the project source dependencies from the repository.
  
  
• copy: Goal that copies a list of artifacts from the repository to defined locations.
  
  
• copy-dependencies: Goal that copies the project dependencies from the repository to a defined location.
  
  
• unpack: Goal that retrieves a list of artifacts from the repository and unpacks them in a defined location.
  
  
• unpack-dependencies: Goal that unpacks the project dependencies from the repository to a defined location.
  
  
• purge-local-repository: Removes the project dependencies from the local repository, and optionally re-resolves them.
  
  
• build-classpath: This goal will output a classpath string of dependencies from the local repository to a file or log.
  
  
• get: Resolves a single artifact, eventually transitively, from the specified remote repositories.
  
  
• go-offline: Goal that resolves all project dependencies, including plugins and reports and their dependencies.
  
  
• properties: Goal that sets a property pointing to the artifact file for each project dependency.
  
  

Here are some examples of maven-dependency-plugin usage:
$ mvn dependency:analyze $ mvn dependency:resolve $ mvn dependency:tree $ mvn dependency:purge-local-repository
