An possible "fix" should be too simple as modify
RemoteCatalogArchetypeDataSource:
```java
@Named("remote-catalog")
@Singleton
public class RemoteCatalogArchetypeDataSource extends
CatalogArchetypeDataSource implements ArchetypeDataSource {
private static final Logger LOGGER =
LoggerFactory.getLogger(RemoteCatalogArchetypeDataSource.class);
@Inject
private RepositorySystem repositorySystem;
/**
* Id of the repository used to download catalog file. Proxy or
authentication info can
* be setup in settings.xml.
*/
public static final String ARCHETYPE_REPOSITORY_ID = "archetype";
public static final String CENTRAL_REPOSITORY_ID = "central";
@Override
public ArchetypeCatalog getArchetypeCatalog(
RepositorySystemSession repositorySession,
List<RemoteRepository> remoteRepositories)
throws ArchetypeDataSourceException {
ArchetypeCatalog mergedArchetypeCatalogs = new ArchetypeCatalog();
for(RemoteRepository repository : remoteRepositories) {
ArchetypeCatalog catalog =
getArchetypeCatalog(repositorySession, repository);
mergedArchetypeCatalogs.getArchetypes().addAll(catalog.getArchetypes());
}
return mergedArchetypeCatalogs;
}
private ArchetypeCatalog getArchetypeCatalog(
RepositorySystemSession repositorySession, RemoteRepository
repository)
throws ArchetypeDataSourceException {
Optional<MetadataResult> optMetadataResult =
requestMetadata(repositorySession, repository);
if(!optMetadataResult.isPresent()) {
return new ArchetypeCatalog();
}
try {
return readCatalog(
new
XmlStreamReader(optMetadataResult.get().getMetadata().getFile())
);
} catch (IOException e) {
throw new ArchetypeDataSourceException(e);
}
}
private Optional<MetadataResult> requestMetadata(RepositorySystemSession
repositorySession, RemoteRepository remoteRepository) {
if(!isArchetypeCatalogRepository(remoteRepository)) {
return Optional.empty();
}
MetadataRequest request = new MetadataRequest();
request.setRepository(remoteRepository);
request.setMetadata(new DefaultMetadata(ARCHETYPE_CATALOG_FILENAME,
Metadata.Nature.RELEASE));
MetadataResult metadataResult = repositorySystem
.resolveMetadata(repositorySession,
Collections.singletonList(request))
.get(0);
if (metadataResult.isResolved()) {
return Optional.of(metadataResult);
} else {
LOGGER.error("No {} had been resolved for repository {}",
ARCHETYPE_CATALOG_FILENAME, remoteRepository.getId(),
metadataResult.getException()
);
return Optional.empty();
}
}
private boolean isArchetypeCatalogRepository(RemoteRepository
remoteRepository) {
if (remoteRepository == null || remoteRepository.getId() == null) {
return false;
}
return ARCHETYPE_REPOSITORY_ID.equals(remoteRepository.getId())
