無法解決Maven站點插件或其中一個依賴關係

-1

我處於受限網絡中，該網絡不允許從互聯網下載文件，因此我們運行了本地Nexus服務器。無法解決Maven站點插件或其中一個依賴關係

白名單代理是不是一種選擇

我需要更新我們常見的Java庫庫，我已成功地創建用於上傳新的文物承上啓下的過程。

使用的settings.xml允許連接到中央
下載使用新依賴關係的POM所有新的文物宣佈
此下載所有罐子/勁歌到~/.m2/repository。我有一個將版本庫內容複製到另一個臨時目錄的python腳本，然後它遍歷這個目錄併爲它遇到的每個jar/pom運行mvn deploy:deploy-file。
然後我切換我的settings.xml，只有一個只允許連接到nexus而不是中央。

理論上，這聽起來不錯，但，當我運行mvn dependency:resolve與當地的settings.xml我得到以下

它解析相關的一些Maven插件的問題，我已經試圖通過尋找插件poms和檢查看看我有Nexus中的依賴關係，但我顯然仍然缺少一些。

有沒有簡單的方法來查看它無法解決哪些依賴關係？

這裏是我的settings.xml

您處於一個並不罕見的受限制網絡中。但是您的連接不會提供正確的文件以使構建正常工作......這意味着您的連接必須能夠從互聯網（Maven Central）下載這些文件。 – khmarbaise

是的，Nexus不具備的文件是從可以訪問互聯網的機器下載的，然後將這些文件部署到Nexus – PDStat

所以運行mvn dependency:resolve -X給了我更多的具體細節

很好，您回答了您自己的問題。不幸的是，答案對其他用戶來說並不是很有用，因爲它不包含這些「具體細節」。你介意添加它們嗎？ – gillesB
