Is there or how to display all available plugin’s goals and parameters (with explanation) in Maven? For example,maven-eclipse “mvn eclipse:eclipse” plugin, how do i know what are the available goals and parameters of it?

Yes, i can always Google it and find the information in the maven-eclipse plugin’s website, but is there a shortcut for it?


You can use Maven help plugin, describe goal, to display the entire available goals and parameter for a plugin.

For example,

1. mvn help:describe -Dplugin=eclipse

List all of the available goals of maven-eclipse plugin.

mvn help:describe -Dplugin=eclipse

Here’s the output …

//... omitted for readable purpose

    M2Elipse plugin.
  Deprecated. No reason given
  Description: Generates MyEclipse configuration files
  Deprecated. No reason given

    the file .websettings

2. mvn help:describe -Dplugin=eclipse -Dmojo=eclipse

Display the detail of “eclipse” parameter of maven-eclipse plugin, with full explanation.

mvn help:describe -Dplugin=eclipse -Dmojo=eclipse -Dfull=true
mojo” is means the parameter of plugin.

Here’s the output …
