消息告诉你，这名失踪的JAR不是你指着仓库中。我建议去回购并确认它。这可能是你要求的版本不正确。 – duffymo

将输出添加为文本而不是图像 – Jens

为什么要使用RC而不是发布的弹簧版本 – Jens

您需要将此回购添加到您的POM文件：

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

我可以知道那是什么。所以我应该保留其他依赖关系 –

由于您正在使用的spring-core版本尚未发布，即它是一个候选版本（RC 5.0.0.RC3），它们存储在Spring存储库中。 – Sam

非常感谢。 –
