Answer 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;但它应该自动下载，...你是否处于离线模式？如果您在上线并执行它，它应该自动下载缺少的依赖项。

Answer 2

我的问题在于POM.XML文件中定义的存储库。我删除它们以便它使用默认的repo并解决了我的问题。

Answer 3

当存储库出现问题时，我发生了这种情况，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。

无法执行目标org.apache.maven.plugins：maven-resources-plugin：2.5：资源
