【maven插件】maven-help-plugin
2024-04-04 06:15:43
前言
- Apache Maven 3.5.0
- OS: Windows 7, v.6.1, x86_64 / win32
- org.apache.maven.plugins:maven-help-plugin:3.2.0
- http://maven.apache.org/plugins/maven-help-plugin/index.html
Goals Overview
The Help Plugin has 7 goals:
- help:active-profiles lists the profiles which are currently active for the build.
- help:all-profiles lists the available profiles under the current project.
- help:describe describes the attributes of a Plugin and/or a Mojo (Maven plain Old Java Object).
- help:effective-pom displays the effective POM as an XML for the current build, with the active profiles factored in. If verbose, a
comment is added to each XML element describing the origin of the
line.- help:effective-settings displays the calculated settings as an XML for the 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:system displays a list of the platform details like system properties and environment variables.
