Maven Grails:无法读取工件描述符

在BuildConfig.groovy中使用EasyGrid插件时，在将插件添加到BuildConfig.groovy中之后，我无法清理和运行插件。面对这样的错误信息，该怎么做才能摆脱这个pls

BuildConfig.groovy插件的更改{

// EasyGrid plugin http://grails.org/plugin/easygrid
        compile ":easygrid:1.6.2"
        // For minimum functionality you need: jquery-ui and the export plugins.
        // Export Plugin http://grails.org/plugin/export
        compile ":export:1.5"
        // jQuery UI Plugin http://grails.org/plugin/jquery-ui
        compile ":jquery-ui:1.10.3"
        // For google visualization you also need google-visualization
        // Google Visualization API Plugin http://grails.org/plugin/google-visualization
        compile ":google-visualization:0.7"

更改后的错误消息

更改插件的顺序，我打赌同样的错误会发生在：export:1.5。看起来你的代理问题没有完全解决。我已经添加了代理设置，能够在没有这些插件的情况下执行示例项目，但当我尝试使用这些插件时，只会遇到问题。需要更改什么请详细说明。我已经查看了插件页面并找到了t插件版本已经是

1.6.3

。可能旧的插件

1.6.2

已经被删除。这是一个不好的建议，但可能是。
