ブラウザでリポジトリの URL ( http://repo.opennms.org/content/repositories/opennms-repo/ ) に問題なくアクセスできます。ただし、インデックスへの URL ( http://repo.opennms.org/content/repositories/opennms-repo/.index/nexus-maven-repository-index.71.gz ) は壊れています。
Nexus/Maven はインデックス ファイルへの URL をどのように決定しますか? これは Maven/Nexus の問題ですか、それともリポジトリの問題ですか?
