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

【中文标题】Maven:缺少工件 org.springframework:spring:jar:4.2.6【英文标题】:Maven: missing artifact org.springframework:spring:jar:4.2.6 【发布时间】:2016-09-13 13:07:44 【问题描述】:

我在 SpringToolSuite 中有一个动态 Web 项目。 它被转换为一个 Maven 项目。

我遇到了问题:

遗漏的工件 org.springframework:spring.jar:4.2.6

我已经尝试清理、重建和运行该项目。 它给出:

读取文件时出错 C:\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)

我不明白为什么在我使用 Maven 时它要求提供 jar 文件?

我已经看到了这个post,但不知何故我无法解决我的问题。

当我执行时

mvn 全新安装

在我得到的项目根目录下:

我还检查了我的代理设置。 eclipse 中的活动提供者设置为“本机”,我没有通过代理连接

目录中

~/.m2/settings.xml

main is org.apache.maven.cli.MavenCli from plexus.core

set maven.home default $user.home/m2

[plexus.core]
optionally $maven.home/lib/ext/*.jar
load       $maven.home/lib/*.jar
load       $maven.home/conf/logging

【问题讨论】:

没有spring.jar,所以永远找不到。从 Spring 3.0 开始,只有单独的模块(spring-beans、spring-context 等)可用。 您可以使用mvn clean install -X 跟踪问题以获取详细信息。 【参考方案1】:

我很确定没有名为“弹簧”的神器

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring</artifactId>           <!-- *** spring doesn't *** exist  -->
    <version>4.2.6</version>
</dependency>

根据你需要的Spring组件,你基本上应该包括这些依赖:

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

在我的 Spring 项目中,我通过 BOM(材料清单)包含 Spring 工件:

<properties>
    <spring.version>4.2.6.RELEASE</spring.version>
</properties>

<dependencyManagement>
    <dependencies>
        <dependency>

【讨论】:

由于某种原因,尽管我正在使用您的代码,但我又遇到了同样的问题。我已经更新了我的问题。你能看一下吗? @jublikon 有一些事情你可以尝试...首先:关闭eclipse,打开命令行窗口,进入项目目录(与pom.xml 所在的位置相同)并执行@987654326 @。会发生什么? @jublikon second:在 eclipse 和 maven 的 ~/.m2/settings.xml 中检查您的代理设置@ 感谢您的回答。我已经检查了您的建议并更新了我之前的帖子。 @jublikon 你的pom.xml 有问题。请显示完整的pom.xml ...我会更新我的答案,请查看&lt;properties&gt;【参考方案2】:

对我有用的是我删除了

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

然后在我的项目中运行mvn clean install 命令。

这样 Maven 下载了以前我无法识别的真实 .jar 文件。

【讨论】:

对我来说,删除/Users/username/.m2/repository/org/springframework 目录并按照您的后一个解决方案进行操作。【参考方案3】:

默认情况下,Maven 会将所需的依赖项下载到您的本地存储库,以便下次可以更快地访问它们。也许依赖项已损坏或从本地磁盘中删除?您是否检查过 C:\Users\jublikon.m2\repository\org\springframework\spring\4.2.6\spring-4.2.6.jar 确实存在并且是有效的 spring jar 文件?

【讨论】:

我看到有两个文件:spring-4.2.6.jar.lastUpdated 和 spring-4.2.6.pom.lastUpdated。 taht 'lastUpdated' 文件是有效的 jar 文件吗? 不,所以您的 Maven 没有获取所需的依赖项。尝试在您的项目上运行 mvn clean install 并检查它是否正在下载任何工件 - 如果没有,您应该会收到一个错误,说明问题出在哪里。或者看看@Ulrich 的答案,这很可能是你的问题 - 无效的依赖描述 我认为您遇到了 Eclipse 的怪事。删除 C:\Users\jublikon.m2\repository\org\springframework\spring\4.2.6 目录并在项目上运行 mvn clean install。这将强制 maven 下载真正的 jar,而不是说“我之前尝试过,但没有用”。【参考方案4】:

对我有用的是我从 mvnrepository 下载了 jar 文件,我从构建路径添加了它们,然后我在 Maven 构建中进行了干净编译安装,然后验证项目,然后更新项目,错误就消失了。

【讨论】:

【参考方案5】:

对于 spring 框架,我在 pom.xml 文件中使用了以下依赖项

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>4.3.2RELEASE</version>
    <scope>test</scope>
</dependency>

但它给了我错误

缺少工件 org.springframework.boot:spring-boot-starter-test:jar:4.3.2.RELEASE

但是当我将版本更改为最新版本时,错误已消除。

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>5.2.1.RELEASE</version>
    <scope>test</scope>
</dependency>

所以尝试使用最新版本。

【讨论】:

【参考方案6】:

此问题是因为所需的 .jar 文件在 .m2 存储库中不可用。

    右击项目-&gt;Maven -&gt;project Update

    如果您使用工作组织中提供的settings.xml,则删除该settings.xml 并重复步骤1。 当您放置 settings.xml 时,它总是会尝试从组织存储库下载所需的 .jar 文件。
