我使用Eclipse Aether，我从https存储库下载工件时遇到问题。 （例如：https://jitpack.io）。 以下代码：
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 );
Code I从这个aether-demo存储库获取。当我在aether-demo项目中运行它时，它工作正常但是当我在我的测试项目中运行类的副本时，它给了我这个例外：
