Eclipse Aether从https仓库下载工件

Question

我使用Eclipse Aether，并且从https仓库下载工件时遇到问题。 （例如：https://jitpack.io）。 下面的代码：

RepositorySystem system = Booter.newRepositorySystem(); 
    RepositorySystemSession session = Booter.newRepositorySystemSession(system); 
    Artifact artifact = new DefaultArtifact("com.github.rubenlagus:TelegramBots:2.4.0"); 
    List<RemoteRepository> reps = Lists.newArrayList(); 
    RemoteRepository repository = new RemoteRepository.Builder(
      "jitpack", "default", "https://jitpack.io").build(); 
    reps.add(repository); 
    reps.addAll(Booter.newRepositories(system, session)); 
    ArtifactRequest artifactRequest = new ArtifactRequest(); 
    artifactRequest.setArtifact(artifact); 

    artifactRequest.setRepositories(reps); 

    ArtifactResult artifactResult = system.resolveArtifact(session, artifactRequest); 

代码我需要从这个蓝天 - 演示存储库。当我运行这个溶于乙醚，示范项目，它工作正常，但是当我在我的测试项目运行的类副本，它给我这个例外：
