在JAVA代码里如何获取MavenProject对象

    org.apache.maven.project.MavenProject对象是maven插件里在MAVEN运行时自动会获取到的，但是我现在写了个自动化部署环境的代码通过继承AbstractMojo的一个testMojo类进行MavenProject对象的操作时里面是NULL，有没有什么办法能获取到这个MavenProject对象呢？
    我想手动调用execute()方法来获取几个我需要的信息，我的代码是：
    @SuppressWarnings("unchecked")
public class GenerateTriggerMojo extends AbstractMojo {

/**
* @parameter
*/
private List<String> searchPackageNames;

/**
* @parameter expression="${project}"
*/
private MavenProject mavenProject;

@Override
public void execute() throws MojoExecutionException, MojoFailureException {
searchPackageNames=null;
//Model model=new Model();
//model.setArtifactId("test.mojo");
//mavenProject=new MavenProject(model);
//mavenProject.setArtifactId("test.mojo");
//File file =new File("Volumes/MacHD/Users/john/Documents/workspace/MojoTest");
//mavenProject.setFile(file);
//mavenProject.setGroupId("com.java");
//init();
String currentModule = mavenProject.getArtifactId();
List<String> classpathElementList = (List<String>) mavenProject.getCompileClasspathElements();
               String basedir=mavenProject.getBasedir().toString();
}

}

试试：(MavenProject)getPluginContext().get("project");

谢谢啊，我试了不行，还是抛空指针，因为我是直接在JAVA代码里调用这个GenerateTriggerMojo这个类的execute()，不是通过mvn命令运行，所以应该超类里的方法为空

也就是说有什么方法能脱离mvn命令，直接通过JAVA代码调用来初始化这个对象或者通过什么方式能初始化这个对象呢？

我有写过一个小工具，供你参考下，主要关注这个类所属的模块来解析MavenXpp3Reader

 Model model = null;
        FileReader reader = null;
        MavenXpp3Reader mavenreader = new MavenXpp3Reader();
        String pomfile = destFile;

        reader = new FileReader(pomfile);
        model = mavenreader.read(reader);
        model.setPomFile(new File(pomfile));

        // exclude 此模块的依赖的本地模块
        UpDependency exit = new UpDependency();
        exit.setArtifactId(model.getArtifactId());
        exit.setGroupId(model.getGroupId());
        exit.setVersion(model.getVersion());
        po.addexistDependency(exit);

        // parser Root
        po.setDependencys(ParserUtils.parserDependency(model.getDependencies()));
        if (model.getDependencyManagement() != null) {
            po.setDependencyManagements(ParserUtils.parserDependency(model.getDependencyManagement().getDependencies()));
        }
        if (model.getBuild() != null && model.getBuild().getPluginManagement() != null) {
            po.setPluginManagements(ParserUtils.parserPlugin(model.getBuild().getPluginManagement().getPlugins()));
        }
        if (model.getBuild() != null) {
            po.setPlugins(ParserUtils.parserPlugin(model.getBuild().getPlugins()));
        }
        log.debug("parser profile");
        // parser profile
        List<Profile> pfs = model.getProfiles();

        for (Profile pf : pfs) {
            po.setDependencys(ParserUtils.parserDependency(pf.getDependencies()));
            if (pf.getDependencyManagement() != null) {
                po.setDependencyManagements(ParserUtils
                        .parserDependency(pf.getDependencyManagement().getDependencies()));
            }
            if (pf.getBuild() != null) {
                po.setPlugins(ParserUtils.parserPlugin(pf.getBuild().getPlugins()));
                if (pf.getBuild().getPluginManagement() != null) {
                    po.setPluginManagements(ParserUtils.parserPlugin(pf.getBuild().getPluginManagement().getPlugins()));
                }
            }
        }

貌似可以啊，非常感谢，我先试试啊
