Posted 2020-06-15

mvn命令格式：

You must specify a valid lifecycle phase 
or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>.

第一种格式：lifecycle phase 

Available lifecycle phases are: 
default生命周期    validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, 
clean生命周期    pre-clean, clean, post-clean, 
site生命周期    pre-site, site, post-site, site-deploy.

 

第二种格式：a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>

查看help插件的帮助信息
mvn help:help
[INFO] Maven Help Plugin 2.2
  The Maven Help plugin provides goals aimed at helping to make sense out of the
  build environment. It includes the ability to view the effective POM and
  settings files, after inheritance and active profiles have been applied, as
  well as a describe a particular plugin goal to give usage information.

This plugin has 9 goals:

help:active-profiles
  Displays a list of the profiles which are currently active for this build.

help:all-profiles
  Displays a list of available profiles under the current project.
  Note: it will list all profiles for a project. If a profile comes up with a
  status inactive then there might be a need to set profile activation
  switches/property.

help:describe
  Displays a list of the attributes for a Maven Plugin and/or goals (aka Mojo -
  Maven plain Old Java Object).

help:effective-pom
  Displays the effective POM as an XML for this build, with the active profiles
  factored in.

help:effective-settings
  Displays the calculated settings as XML for this project, given any profile
  enhancement and the inheritance of the global settings into the user-level
  settings.

help:evaluate
  Evaluates Maven expressions given by the user in an interactive mode.

help:expressions
  Displays the supported Plugin expressions used by Maven.

help:help
  Display help information on maven-help-plugin.
  Call mvn help:help -Ddetail=true -Dgoal=<goal-name> to display parameter
  details.

help:system
  Displays a list of the platform details like system properties and environment
  variables.

 

查看dependency的帮助信息
mvn dependency:help

[INFO] Apache Maven Dependency Plugin 2.10
Provides utility goals to work with dependencies like copying, unpacking,
analyzing, resolving and many more.

This plugin has 22 goals:

dependency:analyze
Analyzes the dependencies of this project and determines which are: used and
declared; used and undeclared; unused and declared. This goal is intended to
be used standalone, thus it always executes the test-compile phase - use the
dependency:analyze-only goal instead when participating in the build
lifecycle.
By default, maven-dependency-analyzer is used to perform the analysis, with
limitations due to the fact that it works at bytecode level, but any analyzer
can be plugged in through analyzer parameter.
。。。。。
dependency:build-classpath
This goal will output a classpath string of dependencies from the local
repository to a file or log.

dependency:copy
Goal that copies a list of artifacts from the repository to defined locations.

dependency:copy-dependencies
Goal that copies the project dependencies from the repository to a defined
location.

dependency:display-ancestors
Displays all ancestor POMs of the project. This may be useful in a continuous
integration system where you want to know all parent poms of the project.

dependency:get
Resolves a single artifact, eventually transitively, from the specified remote
repositories. Caveat: will always check thecentral repository defined in the
super pom. You could use a mirror entry in your settings.xml

dependency:go-offline
Goal that resolves all project dependencies, including plugins and reports and
their dependencies.

dependency:help
Display help information on maven-dependency-plugin.
Call mvn dependency:help -Ddetail=true -Dgoal=<goal-name> to display parameter
details.

dependency:list
Displays the list of dependencies for this project.

dependency:list-repositories
Goal that resolves all project dependencies and then lists the repositories
used by the build and by the transitive dependencies

dependency:properties
Goal that sets a property pointing to the artifact file for each project
dependency. For each dependency (direct and transitive) a project property
will be set which follows the groupId:artifactId:type:[classifier] form and
contains the path to the resolved artifact.

dependency:purge-local-repository
Remove the project dependencies from the local repository, and optionally
re-resolve them.

dependency:resolve
Goal that resolves the project dependencies from the repository.

dependency:resolve-plugins
Goal that resolves all project plugins and reports and their dependencies.

dependency:sources
Goal that resolves the project source dependencies from the repository.

dependency:tree
Displays the dependency tree for this project.
