無法讀取org.springframework的工件描述符：spring-core：jar

我試圖將maven依賴關係下載到我的netbeans構建maven web應用程序。 ince我無法通過IDE更新依賴項我試圖使用它來執行此操作無法讀取org.springframework的工件描述符：spring-core：jar

mvn clean install

命令槽cmd。
但我仍然有同樣的錯誤。

請幫忙。我試圖弄清楚這幾天。（Internet連接工作相當精細。）
感謝您

消息告訴你，這名失蹤的JAR不是你指着倉庫中。我建議去回購並確認它。這可能是你要求的版本不正確。 – duffymo

將輸出添加爲文本而不是圖像 – Jens

爲什麼要使用RC而不是發佈的彈簧版本 – Jens

您需要將此回購添加到您的POM文件：

<repositories> 
    <repository> 
    <id>repository.spring.milestone</id> 
    <name>Spring Milestone Repository</name> 
    <url>http://repo.spring.io/milestone</url> 
    </repository> 
</repositories>

我可以知道那是什麼。所以我應該保留其他依賴關係 –

由於您正在使用的spring-core版本尚未發佈，即它是一個候選版本（RC 5.0.0.RC3），它們存儲在Spring存儲庫中。 – Sam

非常感謝。 –
