异常 org.eclipse.aether.resolution.DependencyResolutionException：无法读取 ch.qos.logback:logback-classic:jar:1.2.3 的工件描述符

Question

我正在尝试通过此解决方案 [1] 中提到的编程方式获取给定工件的所有 maven 依赖项。

我正在尝试获取 ch.qos.logback:logback-classic:1.2.3 的依赖项。

public static void main(final String[] args) throws Exception {
        DefaultServiceLocator locator = MavenRepositorySystemUtils.newServiceLocator();
        RepositorySystem system = newRepositorySystem(locator);
        RepositorySystemSession session = newSession(system);

        RemoteRepository central = new RemoteRepository.Builder("central", "default", "http://repo1.maven.org/maven2/").build();

        String groupId = "ch.qos.logback";
        String artifactId = "logback-classic";
        String version = "1.2.3";
        String dep = groupId + ":" + artifactId + ":" + version;
        Artifact artifact = new DefaultArtifact(dep);

        CollectRequest collectRequest = new CollectRequest(new Dependency(artifact, JavaScopes.COMPILE), Arrays.asList(central));
        DependencyFilter filter = DependencyFilterUtils.classpathFilter(JavaScopes.COMPILE);
        DependencyRequest request = new DependencyRequest(collectRequest, filter);
        DependencyResult result = system.resolveDependencies(session, request);

        for (ArtifactResult artifactResult : result.getArtifactResults()) {
            System.out.println(artifactResult.getArtifact().getFile());
        }
    }

    private static RepositorySystem newRepositorySystem(DefaultServiceLocator locator) {
        locator.addService(RepositoryConnectorFactory.class, BasicRepositoryConnectorFactory.class);
        locator.addService(TransporterFactory.class, FileTransporterFactory.class);
        locator.addService(TransporterFactory.class, HttpTransporterFactory.class);
        return locator.getService(RepositorySystem.class);
    }

    private static RepositorySystemSession newSession(RepositorySystem system) {
        DefaultRepositorySystemSession session = MavenRepositorySystemUtils.newSession();
        LocalRepository localRepo = new LocalRepository("target/local-repo");
        session.setLocalRepositoryManager(system.newLocalRepositoryManager(session, localRepo));
        return session;
    }

这是我在运行 main 方法时得到的错误堆栈跟踪。

[1]Maven: get all dependencies programmatically

Answer 1

错误在下一行。

RemoteRepository central = new RemoteRepository.Builder("central", "default", "http://repo1.maven.org/maven2/").build();

将 repo maven URL http://repo1.maven.org/maven2/ 更改为 https://repo1.maven.org/maven2/
