测试项目工件

注意：此示例改进了食谱以使用工件处理程序。

有时，您的 Mojo 使用项目工件和 ArtifactHandler 机制。例如，您可能需要过滤 Java 项目，即：

public class MyMojo
    extends AbstractMojo
{
    /**
     * The Maven Project.
     */
    @Component
    protected MavenProject project;

    public void execute()
        throws MojoExecutionException
    {
        ...

        ArtifactHandler artifactHandler = project.getArtifact().getArtifactHandler();
        if ( "java".equals( artifactHandler.getLanguage() ) )
        {
            ...
        }

        ...
     }
}

创建存根

public class MyArtifactHandlerStub
    extends DefaultArtifactHandler
{
    private String language;

    public String getLanguage()
    {
        if ( language == null )
        {
            language = "java";
        }

        return language;
    }

    {

    }
