maven - 无法读取我的本地主机 Nexus 存储库中存在的 Artifact 的 Artifact 描述符

Question

所以我遇到了一个错误 Failed to read artifact descriptor对于已部署到我本地 Nexus 的插件。我检查了 Nexus 上的 pom。
这个插件依赖于 Maven 2.2.1 而我正在考虑 Maven 3.0.4。这可能是个问题吗？

<repositories>
    <repository>
        <id>public</id>
        <url>http://localhost:8081/nexus/content/groups/public</url>
    </repository>
</repositories>

啊发现问题了。我正在使用 <repositories>标签。使用 Maven 3 所以我需要添加 <pluginRepositories>标记到我的 pom 以获得这种依赖

<pluginRepositories>
    <repository>
        <id>public</id>
        <url>http://localhost:8081/nexus/content/groups/public</url>
    </repository>
</pluginRepositories>
