Question

这个问题已经让我头晕了太长时间，所以我真的需要一些专家帮助解决这个问题。

我已经安装了Sonatype Nexus ver 2.0.3，我将它作为我的JavaEE开发存储库，Glassfish类应用程序并配置了maven settings.xml以从nexus repo中读取。每个其他jar都已正确下载并缓存，但每次涉及到org.eclipse.persistence.xxx上的jar时，结果都失败了：

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：代理人
存储库ID：eclipselink
政策：快照
远程存储位置：http://download.eclipse.org/rt/eclipselink/maven.repo/
下载远程索引：错误存储库路径网址：http://localhost:8993/nexus/content/repositories/ecliselink/

至于使用maven的回购，我已经创建了一个组来整理必要的回购：
组名：我的存储库
Group ID：myrepo
在Ordered Group Repository Lists中，我有： - Apache快照
： - 中央
： - Codehaus快照
： - EclipseLink Maven Repository（指的是以前创建的EclipseLink代理）

在我的pom.xml中，剪切的依赖项如下：

        <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>

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nexus获取jar时[这不是链接] http：// localhost：8993 / nexus / content / repositories / eclipselink / org / eclipse / persistence / eclipselink / 2.3.2 / eclipselink-2.3。 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。真的很感激任何帮助。

谢谢。

Answer 1

我找到了一个与“Nexus”一起使用的maven存储库URL：

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

Answer 2

EclipseLink存储库的根目录产生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，而Nexus无法索引存储库。

尝试使用这样的镜像：

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

并查看相关问题

Where did the EclipseLink/Maven repository go to? (again)

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