Means that plugins that you have are conflicting with the ones attempted to be installed. Once it computes the alternate paths, it pops up the next wizard page. you should be able to see what the conflicts are. In this particular case it might be something related to Groovy Eclipse. Try not selecting Groovy and Grails and see if that helps.
意味着您拥有的插件与尝试安装的插件相冲突。一旦它计算出备用路径，它就会弹出下一个向导页面。您应该能够看到冲突是什么。在这种特殊情况下，它可能与 Groovy Eclipse 相关。尽量不要选择 Groovy 和 Grails，看看是否有帮助。
