我已经为此困扰了太久，所以我真的需要一些专家的帮助，他们可以解决这个问题。

我已经安装了 Sonatype Nexus 2.0.3 版，并将它作为我的 JavaEE、Glassfish 类应用程序的开发存储库，并配置了 maven settings.xml 以从 nexus 存储库中读取。其他所有 jar 都已正确下载和缓存，但每次涉及 org.eclipse.persistence.xxx 上的 jar 时，结果都失败了：

这是我配置 nexus 存储库（开源版本）的方式：

我创建了 EclipseLink 的代理：
存储库名称：EclipseLink Maven 存储库
类型：代理
存储库 ID：eclipselink
策略：快照
远程存储位置：http://download.eclipse .org/rt/eclipselink/maven.repo/
下载Remote Indexes: False
Repository Path URL: http://localhost:8993/nexus/content/repositories/ecliselink/


至于使用maven的repo，我自己创建了一个组以汇总必要的存储库：
组名称：我的存储库
组 ID：myrepo
在有序组存储库列表中，我有
：- Apache 快照
：- 中央
:- Codehaus Snapshots
:- EclipseLink Maven Repository (指的是之前创建的 EclipseLink 代理)


在我的 pom.xml 中，依赖的片段如下：

        <dependency>
            <groupId>org.eclipse.persistence</groupId>
            <artifactId>eclipselink</artifactId>
            <version>2.3.2</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.eclipse.persistence</groupId>
            <artifactId>javax.persistence</artifactId>
            <version>2.0.3</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.eclipse.persistence</groupId>
            <artifactId>org.eclipse.persistence.jpa.modelgen.processor</artifactId>
            <version>2.3.2</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.glassfish.appclient</groupId>
            <artifactId>gf-client</artifactId>
            <version>3.1</version>
            <type>pom</type>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>javaee</groupId>
            <artifactId>javaee-api</artifactId>
            <version>5</version>
            <scope>provided</scope>
        </dependency>

在 maven settings.xml 文件中，镜像定义为：

    <mirror>
        <id>MyRepo</id>
        <name>My Repository</name>
        <url>http://localhost:8993/nexus/content/groups/myrepo/</url>
        <mirrorOf>*</mirrorOf>
    </mirror>

只是为了测试其中一个罐子是否存在，我直接调用[这不是链接]http://download.eclipse.org/rt/eclipselink/maven.repo/org/eclipse/persistence/eclipselink/2.3.2 /eclipselink-2.3.2.jar 在浏览器中，jar 就在那里。但是，当我尝试从 [这不是链接]http://localhost:8993/nexus/content/repositories/eclipselink/org/eclipse/persistence/eclipselink/2.3.2/eclipselink-2.3 处的 nexus 获取 jar 时。 2.jar，它的404？！

我已经更新并修复了索引，但所有这些都无济于事。任何帮助都非常感谢。

谢谢你。

我找到了一个适用于“Nexus”的 Maven 存储库 URL：

http://maven.eclipse.org/nexus/content/repositories/Sonatype/

EclipseLink 存储库的根会给出 404 错误（不是在链接特定 jar 时）。这种奇怪的行为可能是问题的根源，Nexus 无法索引存储库。

尝试使用这样的镜子：

http://linorg.usp.br/eclipse/rt/eclipselink/maven.repo/

并检查这个相关的问题

EclipseLink/Maven 存储库去了哪里？（再次）
