Question

我正在尝试使用Amazon S3来托管我的Maven工件。我已将以下内容添加到我的pom.xml中：

<distributionManagement>
    <repository>
        <id>maven.xxx.com-release</id>
        <name>AWS S3 Release Repository</name>
        <url>s3://maven.xxx.com/release</url>
    </repository>
    <snapshotRepository>
        <id>maven.xxx.com-snapshot</id>
        <name>AWS S3 Snapshot Repository</name>
        <url>s3://maven.xxx.com/snapshot</url>
    </snapshotRepository>
</distributionManagement>

<build>
    <extensions>
        <extension>
            <groupId>org.springframework.build</groupId>
            <artifactId>aws-maven</artifactId>
            <version>5.0.0.RELEASE</version>
        </extension>
    </extensions>
</build>

这很好用，我的快照存储在S3上。现在我正试图在另一个项目中引用工件：

<repositories>
    <repository>
        <id>maven.xxx.com-release</id>
        <name>AWS S3 Release Repository</name>
        <url>s3://maven.xxx.com/release</url>
    </repository>
    <repository>
        <id>maven.xxx.com-snapshot</id>
        <name>AWS S3 Snapshot Repository</name>
        <url>s3://maven.xxx.com/snapshot</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>

<build>
    <extensions>
        <extension>
            <groupId>org.springframework.build</groupId>
            <artifactId>aws-maven</artifactId>
            <version>5.0.0.RELEASE</version>
        </extension>
    </extensions>
</build>

当我运行$ mvn deploy -X时，我收到以下错误：

无法将工件com.xxx:parent-pom:pom:1.4.11-20140722.193312-1从/向maven.xxx.com-snapshot传输（s3：//maven.xxx.com/snapshot）：没有连接器可用于访问存储库maven.xxx.com-snapshot（s3：//maven.xxx.com/snapshot）类型为default，使用可用工厂WagonRepositoryConnectorFactory和'parent.relativePath'指向错误的本地POM

所以我可以编写工件（凭证显然是正确的）但不读它们？我必须忽略一些简单的事情，但我找不到它。

Answer 1

我创建了一个如何将S3存储桶用作maven存储库的示例项目。

<强> https://github.com/wbinglee/maven-s3-repo

从您的配置中，我没有看到明显的问题。您可以将项目配置与上面的示例项目进行比较。如果找不到问题，可能需要共享完整的pom.xml。

将S3用作maven存储库的其他选项是直接使用http架构并将S3存储桶配置为静态Web主机。它还包含在以上示例项目中，并在README中进行了必要的配置。

然后您可以配置您的maven存储库配置，如下所示：

<repositories>
    <repository>
        <id>maven.xxx.com-release</id>
        <name>AWS S3 Release Repository</name>
        <url>http://maven.xxx.com.s3-website-ap-southeast-2.amazonaws.com/release</url>
    </repository>
    <repository>
        <id>maven.xxx.com-snapshot</id>
        <name>AWS S3 Snapshot Repository</name>
        <url>http://maven.xxx.com.s3-website-ap-southeast-2.amazonaws.com/snapshot</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>

希望有所帮助。

Answer 2

我无法摆脱异常没有连接器可用于使用可用工厂访问类型为default的存储库maven.xxx.com-snapshot（s3：//maven.xxx.com/snapshot） WagonRepositoryConnectorFactory 即可。原因是，我使用远程/独立<parent> POM和Maven似乎首先尝试加载它，然后才添加扩展。这就是错误发生的原因。

所以，我需要回到HTTP（S）。但是，我不想公开我的工件，这排除了S3的静态网站托管。相反，我使用http://www.s3auth.com，它提供HTTP基本身份验证并且运行良好。

唯一需要注意的事项是：

您通过S3旅行车上传 - 因此您需要在settings.xml中提供这些凭据。
您可以通过HTTP下载 - 因此您还需要在settings.xml中使用基本身份验证凭据。
因此，我已经为S3版本+快照参考创建了唯一的ID，并为HTTP版本+快照参考创建了唯一的ID。

不幸的是，它目前还不支持HTTPS，这是一个主要的缺点。

Answer 3

如果像我一样，由于使用了远程父POM而Maven尝试在添加扩展程序之前加载它（因此无法读取s3：//），您就会收到此消息，请参阅https://github.com/spring-projects/aws-maven/issues/25#issuecomment-112031441

这样做会为我修复它并允许我保持父远程并让maven仍然通过s3 url和IAM权限解析它。

Answer 4

从Maven 3.3.1开始，您可以简单地创建一个名为${maven.projectBasedir}/.mvn/extensions.xml的文件。这将被首先加载，并像一个魔术。请参阅this answer或直接检查the release notes了解更多详细信息。

将Maven依赖项部署到S3：没有可用的连接器
