java - Maven 3插件：列出项目的依赖项

Question

我正在尝试创建一个 maven 3 插件，该插件应该解析项目的每个依赖项和传递依赖项，并列出工件，最好带有指向本地 maven 存储库中 jar 文件的链接。我运气不太好。

之后我必须处理依赖项，依赖项和树插件对我来说并不是一个真正的选择。我需要创建一个可以处理依赖项工件的自定义插件。

我尝试使用 DependencyGraphBuilder 创建一个插件，但没有成功：

@Parameter(defaultValue = "${project.build.directory}", property = "outputDir", required = true)
private File outputDirectory;

@Parameter(defaultValue = "${project}", readonly = true, required = true)
private MavenProject project;

@Parameter(defaultValue = "${session}", readonly = true, required = true)
private MavenSession session;

@Component(hint = "maven3")
private DependencyGraphBuilder dependencyGraphBuilder;

@Override
public void execute() throws MojoExecutionException, MojoFailureException {
    File targetDir = outputDirectory;

    if (!targetDir.exists()) {
        targetDir.mkdirs();
    }

    ProjectBuildingRequest buildingRequest = new DefaultProjectBuildingRequest(session.getProjectBuildingRequest());
    buildingRequest.setProject(project);
    try {
        try (PrintWriter writer = new PrintWriter(new File(outputDirectory, "output"))) {
            writer.println("I did shit");
        }

        DependencyNode depenGraphRootNode = dependencyGraphBuilder.buildDependencyGraph(buildingRequest, null);
        CollectingDependencyNodeVisitor visitor = new CollectingDependencyNodeVisitor();
        depenGraphRootNode.accept(visitor);
        List<DependencyNode> children = visitor.getNodes();
        for (DependencyNode node : children) {
            System.out.println(node.getArtifact().getGroupId() + " " + node.getArtifact().getArtifactId());
            try (PrintWriter writer = new PrintWriter(new File(outputDirectory, "output"))) {
                writer.println(node.getArtifact().getGroupId() + " " + node.getArtifact().getArtifactId());
            }
        }
    } catch (Exception ex) {

    }
}

例如，我得到了一些不同的例外，具体取决于我的 pom 中的依赖版本

java.lang.NoSuchMethodError: org.apache.maven.artifact.versioning.DefaultArtifactVersion.compareTo(Lorg/apache/maven/artifact/versioning/ArtifactVersion;)我

和

java.lang.NoClassDefFoundError: org/eclipse/aether/RepositorySystemSession

有人可以为我提供一个工作依赖设置以使 DependencyGraphBuilder 工作，或者提供一种解析编译项目依赖项的不同方式吗？
