【问题描述】：

我正在使用带有 Maven 插件的 Maven 3.0.5 和 Spring Tool Source 3.2 安装。当我尝试执行“运行方式---> Maven 安装”时，我得到了 以下错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:2.5:resources (default-resources) on project mavencxf: Execution default-resources of goal org.apache.maven.plugins:maven-resources-plugin:2.5:resources failed: A required class was missing while executing org.apache.maven.plugins:maven-resources-plugin:2.5:resources: org/codehaus/plexus/util/Scanner

【问题讨论】：

听起来可能是您的 Maven 安装之间的不匹配。检查 Eclipse 中的 Maven 设置。 mvn install 是否在命令行上工作。如果没有， mvn -e install 提供什么。

除了上述检查你为什么使用旧版本的 maven-resources-plugin。

【参考方案1】：

A required class was missing while executing org.apache.maven.plugins:maven-resources-plugin:2.5:resources: org/codehaus/plexus/util/Scanner

资源插件缺少依赖项；但它应该会自动下载，...您是否处于 离线 模式？如果你上线一次并执行它，它应该会自动下载缺少的依赖项。

【参考方案2】：

我的问题在于 POM.XML 文件中定义的存储库。我删除了它们，以便它使用默认存储库并解决了我的问题。

【参考方案3】：

当存储库出现问题时，我曾经发生过这种情况，然后即使我再次运行 maven，它仍然失败。

解决方案：

删除maven repo ~/.m2/repository 然后重新构建

它对我有用。
