我正在使用一個我沒有配置的連接。我在運行 Windows Server 2012 的系統上使用遠程桌面登錄。當我想構建我的 spring-boot 應用程式并運行目標 mvn clean 包時，它會下載幾個依賴項，然后因連接被拒絕錯誤而失敗。我不明白。為什么可以下載前幾個，但不能下載 spring-boot-starter-aop jar？什么連接被拒絕？那個是用來下載otheres的？這是我的錯誤報告：

uj5u.com熱心網友回復：
它不是下載其中任何一個。
如果您查看訂單，實際上第一個失敗了Downloading: http://192.168.1.142:8081/nexus/content/groups/public/org/aspectj/aspectjweaver/1.9.6/aspectjweaver-1.9.6.pom。
它告訴您它正在下載，但是在第一次嘗試期間它無法連接。
我的建議是先在沒有maven的情況下嘗試瀏覽器上的URL，看看是否可以訪問它：http://192.168.1.142:8081/nexus/content/groups/public/在瀏覽器中
如果任何這些依賴項的下載成功，您將看到 (downloading/downloaded)
