java - 在 Sonatype Nexus 和 EclipseLink Maven Repo Proxy 方面需要帮助

Question

我为此苦思冥想了太久，所以我真的很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 ver 2.0.3，并将其作为我的 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，都会失败，结果如下:

[WARNING] The POM for org.eclipse.persistence:eclipselink:jar:2.3.2 is missing, no dependency information available
[WARNING] The POM for org.eclipse.persistence:javax.persistence:jar:2.0.3 is missing, no dependency information available

这是我配置 nexus repo(开源版本)的方式:

我已经为 EclipseLink 创建了一个代理:
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/
下载远程索引:错误
存储库路径 URL:http://localhost:8993/nexus/content/repositories/ecliselink/


关于使用maven的repo，我建了个群把必要的repo汇总:
群组名称:我的资料库
群号:myrepo
在有序组存储库列表中，我有
:- Apache 快照
:- 中央
:- Codehaus 快照
:- EclipseLink Maven Repository(指的是之前创建的 EclipseLink 代理)


在我的 pom.xml 中，依赖项的片段如下:

        <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 jar 是否存在，我直接调用了[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。非常感谢任何帮助。

谢谢。

我找到了一个适用于“Nexus”的 Maven 存储库 URL:
