3 个解决方案

#1

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

在执行org.apache.maven.plugins:maven-resources-plugin:2.5:resources: resources: org/codehaus/plexus/util/Scanner时，缺少一个必需的类

The resources plugin is missing a dependency; But it should download it automatically,... are you in offline mode? If you are go online once and execute it, it should download the missing dependencies automatically.

资源插件缺少一个依赖项;但它应该自动下载，……你处于离线模式吗?如果您上线一次并执行它，它将自动下载丢失的依赖项。

#2

My problem was with the repositories defined in the POM.XML file. I removed them so that it would use the default repo and it solved my issue.

我的问题是POM中定义的存储库。XML文件。我删除了它们，以便它使用默认的repo，它解决了我的问题。

#3

This happened to me once when something went wrong with the repository, and then even if I ran maven again, it still failed.

当存储库出现问题时，这种情况曾经发生在我身上，即使我再次运行maven，它仍然会失败。

Solution:

解决方案:

delete maven repo ~/.m2/repository
回购~ / .m2 /删除maven存储库
and then re-build
然后重建

It works for me.

它适合我。
