Interface Mojo

All Known Implementing Classes:

AbstractMojo

public interface Mojo

This interface forms the contract required for Mojos to interact with the Maven infrastructure.
It features an execute() method, which triggers the Mojo's build-process behavior, and can throw a MojoExecutionException or MojoFailureException if error conditions occur.
Also included is the setLog(...) method, which simply allows Maven to inject a logging mechanism which will allow the Mojo to communicate to the outside world through standard Maven channels.

Method Detail

execute

void execute()
      throws MojoExecutionException,
             MojoFailureException

Perform whatever build-process behavior this Mojo implements.
This is the main trigger for the Mojo inside the Maven system, and allows the Mojo to communicate errors.

Throws:

MojoExecutionException - if an unexpected problem occurs. Throwing this exception causes a "BUILD ERROR" message to be displayed.

MojoFailureException - if an expected problem (such as a compilation failure) occurs. Throwing this exception causes a "BUILD FAILURE" message to be displayed.

setLog

void setLog(Log log)

Inject a standard Maven logging mechanism to allow this Mojo to communicate events and feedback to the user.

Parameters:

log - a new logger

getLog

Log getLog()

Furnish access to the standard Maven logging mechanism which is managed in this base class.

Returns:

a log4j-like logger object which allows plugins to create messages at levels of "debug", "info", "warn", and "error". This logger is the accepted means to display information to the user.
