无法解决maven问题

我对maven是新手，正在努力学习。我目前正在尝试使用maven构建我的grails应用程序。在编译pom时，我遇到了这个错误

Failure to find org.codehaus.groovy:groovy-all:jar:2.4.2 in http://repo.grails.org/grails/core

在阅读了一些maven文档并检查了maven central站点之后，我发现这个jar在maven central位置不可用。因此，我决定用一个可用的jar覆盖这个依赖项。但我还是犯了同样的错误

我的pom文件如下所示

如果有人知道我哪里出了问题，请帮助我

事先非常感谢。

我现在已经开始工作了。GrailsMaven插件2.4.2中有一个bug。升级到2.4.3解决了该问题。感谢所有人对我的查询作出响应。

刚刚从pom中删除了您的存储库条目。您能否更具体地说明如何执行此操作。我对maven有点陌生
