我正在使用Spring工具套件，嵌入了Maven，我在创建一个新的Maven项目时遇到了这个问题。清理存储库和重建，代理settings.xml，指向正确的xml，使用自己的maven等等，我做错了什么？问题的完整描述：

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-
resources-plugin:2.6 or one of its dependencies could not be resolved: 
Failed to read artifact descriptor for org.apache.maven.plugins:maven-
resources-plugin:jar:2.6
