mvn在自動安裝的目錄上失敗

在非自動安裝的文件系統上，「mvn clean」工作（「mvn package」也是如此）。，就會向掛載文件系統，「MVN乾淨」的失敗，以下列方式：mvn在自動安裝的目錄上失敗

很顯然，我失去了某種配置信息，但尋找問題的答案都是我發現的是，我需要刪除〜 /.m2/*，chmod 777〜/ .m2，並確保我的JAVA_HOME是正確的。這些建議都沒有奏效。我錯過了什麼？

有趣的是，Gradle似乎無法在自動安裝的文件系統上工作。

用戶可以創建目錄，文件，更改權限等。「mount」輸出顯示用戶具有「rw」權限：10.10.10.10:/ms/ms.share/services/ps/guest on/nethome/guest類型nfs（** rw **，relatime，vers = 3，rsize = 131072，wsize = 131072，namlen = 255，hard，proto = tcp，timeo = 600，retrans = 2，sec = sys，mountaddr = 10.20.30.70，mountvers = 3，mountport = 2049，mountproto = tcp，local_lock = none，addr = 10.20.30.70） – user2569618

「用戶能夠創建目錄」 - 哪個用戶？你確定它是運行Maven作業的用戶嗎？ –

我相信如此。我可以登錄並執行mkdir〜/ .m2，但是當我刪除〜/ .m2並執行「mvn package」時，maven報告「無法在/ nethome/ /.m2/repository創建本地存儲庫」。我已經給安裝選項添加了「hard，nolock，noac」，但仍然沒有喜悅。 – user2569618

這似乎是一個NFS問題。 JDK委託給本地函數調用Linux，並且底層的系統調用失敗。嘗試將Maven本地存儲庫目錄指向本地文件系統。具體而言，在文件apache-maven-${version}/conf/settings.xml，取消和更新行：

<localRepository>some_local_directory</localRepository>

下似乎解決寫問題。

通過添加「硬，NOLOCK，NOAC」的自動安裝說明，用戶現在能夠運行「MVN」。不幸的是，在本地文件系統上建立1分鐘的時間在自動安裝的文件系統上大約需要15分鐘。但這是另一個問題/ stackoverflow的問題。
