remoteRepositories - A list of remote repositories available.

Method Detail

resolve

public java.lang.ClassLoader resolve(MavenCoordinate mavenCoordinate)
                              throws org.apache.maven.plugin.MojoFailureException,
                                     org.apache.maven.plugin.MojoExecutionException

Resolves a Maven coordinate to a class loader that can load all of the coordinates classes. If a Maven coordinate was resolved previously, the previously created class loader is returned.

Parameters:

mavenCoordinate - The Maven coordinate to resolve.

Returns:

A class loader that references all of the class loader's dependencies and which is a child of this class's class loader.

Throws:

org.apache.maven.plugin.MojoExecutionException - If the user configuration results in an error.

org.apache.maven.plugin.MojoFailureException - If the plugin application raises an error.

doResolve

private java.lang.ClassLoader doResolve(MavenCoordinate mavenCoordinate)
                                 throws org.apache.maven.plugin.MojoExecutionException,
                                        org.apache.maven.plugin.MojoFailureException

Resolves a Maven coordinate to a class loader that can load all of the coordinates classes.

Parameters:

mavenCoordinate - The Maven coordinate to resolve.

Returns:

A class loader that references all of the class loader's dependencies and which is a child of this class's class loader.

Throws:

org.apache.maven.plugin.MojoExecutionException - If the user configuration results in an error.

org.apache.maven.plugin.MojoFailureException - If the plugin application raises an error.
