java - maven中获取完整的依赖图

标签 java maven maven-3

我有 Maven 依赖项的问题。我尝试在我的 maven 插件中有一个完整的依赖关系图，但没有出现一些重复的节点。

我的 maven 项目由:

  • “dependency_test”，4个模块的父项目
  • “mod1”、“mod2”、“mod3”、“mod4”子模块
  • “dependency_test_maven_plugin”，maven 插件项目

这里是不同的 pom.xml 文件:

mod3:

我的依赖图是这样的:

mod1
--mod2
----mod3
----mod4
--mod3

我需要在我的“dependency_test_maven_plugin”插件中包含这个完整的图表。现在，它看起来像:

Mojo 类:

@Mojo(name = "dependency-test-goal", defaultPhase = LifecyclePhase.PROCESS_RESOURCES, requiresDependencyCollection = ResolutionScope.COMPILE_PLUS_RUNTIME, requiresDependencyResolution = ResolutionScope.COMPILE_PLUS_RUNTIME)
public class JLinkMojo extends AbstractMojo {

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

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

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

    ArtifactFilter artifactFilter;
    ProjectBuildingRequest buildingRequest;

    public void execute() throws MojoExecutionException {
        artifactFilter = new ExcludesArtifactFilter(Arrays.asList("com.aned:dependency_test_maven_plugin"));
        buildingRequest = new DefaultProjectBuildingRequest(session.getProjectBuildingRequest());

        buildingRequest.setProject(project);

        try {
            DependencyNode rootNode = dependencyGraphBuilder.buildDependencyGraph(buildingRequest, artifactFilter);
            getLog().info("Start depdendency graph");
            int level = 0;
            displayNode(rootNode, level);
            getLog().info("End depdendency graph");

            CollectingDependencyNodeVisitor visitor = new CollectingDependencyNodeVisitor();
            rootNode.accept(visitor);

            for (DependencyNode dependencyNode : visitor.getNodes()) {
                getLog().info("Start depdendency graph for node " + dependencyNode.getArtifact().getArtifactId());
                displayNode(dependencyNode, level);
                getLog().info("End depdendency graph for node " + dependencyNode.getArtifact().getArtifactId());
            }

        } catch (DependencyGraphBuilderException e) {
            throw new MojoExecutionException("Error", e);
        }
    }

    private void displayNode(DependencyNode rootNode, int level) {
        String indentation = "";
        for (int i = 0; i < level; i++) {
            indentation += "--";
        }
        getLog().info(indentation + rootNode.getArtifact().getArtifactId());

        for (DependencyNode childrenNode : rootNode.getChildren()) {
            displayNode(childrenNode, level + 1);
        }
    }
}

执行时，mojo 跟踪是:

[INFO] --- dependency_test_maven_plugin:1.0.0:dependency-test-goal (default) @ mod1 ---
[INFO] Start depdendency graph
[INFO] mod1
[INFO] --mod2
[INFO] ----mod4
[INFO] --mod3
[INFO] End depdendency graph
[INFO] Start depdendency graph for node mod1
[INFO] mod1
[INFO] --mod2
[INFO] ----mod4
[INFO] --mod3
[INFO] End depdendency graph for node mod1
[INFO] Start depdendency graph for node mod2
[INFO] mod2
[INFO] --mod4
[INFO] End depdendency graph for node mod2
[INFO] Start depdendency graph for node mod4
[INFO] mod4
[INFO] End depdendency graph for node mod4
[INFO] Start depdendency graph for node mod3
[INFO] mod3
[INFO] End depdendency graph for node mod3

因此，在 visitor.getNodes 跟踪中的依赖关系图跟踪中，从 mod2 到 mod3 的依赖关系是不可见的(我认为这是因为它是从 mod1 到 mod3 的链接的副本)。 有没有办法获得完整的跟踪:

mod1
--mod2
----mod3
----mod4
--mod3

编辑 1:如果我尝试在我的父项目上使用 dependency:tree，我会得到相同的结果:

谢谢，

不确定这是否是您要查找的内容，但您可以使用以下方法查看所有依赖项(包括重复项):

mvn dependency:tree -Dverbose
