Maven:缺少工件org.springframework:spring:jar:4.2.6

Maven:缺少工件org.springframework:spring:jar:4.2.6

jub*_*kon 4 java eclipse spring spring-mvc maven

我在SpringToolSuite中有一个动态Web项目.它被转换为Maven项目.

我遇到了这个问题:

Mising artifact org.springframework:spring.jar:4.2.6

我已经尝试过清理,重建和运行项目.它给:

读取文件C时出错:\ Users\jublikon.m2\repository\org\springframework\spring\4.2.6\spring-4.2.6.jar C:\ Users\jublikon.m2\repository\org\springframework\spring\4.2. 6\spring-4.2.6.jar(系统找不到指定的文件)

我不明白为什么我在使用Maven时要求jar文件？

的pom.xml

我已经看过这篇文章,但不知怎的,我无法解决我的问题.

当我执行

mvn clean install

在我得到的项目的根目录中:

我还检查了我的代理设置.eclipse中的活动提供程序设置为"native",我没有通过代理连接

我很确定没有名为"spring"的神器

    <groupId>org.springframework</groupId>
    <artifactId>spring</artifactId>           <!-- *** spring doesn't *** exist  -->

根据您需要的Spring组件,您应该基本上包含这些依赖项:

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.2.6.RELEASE</version>

对我有用的是我删除了

/Users/username/.m2/repository/org/springframework/spring/ 目录

然后mvn clean install在我的项目中运行命令。

这样，Maven 就下载了以前我无法识别的真实 .jar 文件。

对我来说，删除 ```/Users/username/.m2/repository/org/springframework``` 目录并遵循您的后一个解决方案是有效的。 (2认同)
