有人能帮我吗？

您的Eclipse版本可能比3.7.x更新。因此，请改用更新站点

@Jarrod:No，问题是“googlepluginforeclipse”无法安装！无法安装它，因为它需要

org.eclipse.platform.feature.group[3.7.0,3.8.0）

。我几乎不理解这个错误中的任何内容。但是，取消选择您提到的这两件事中的任何一件或两者都无助于安装它？我完全不知道，为什么这个问题被关闭。问题的答案一点也不明显，如果您不知道Eclipse的插件，错误消息几乎无法读取结构、功能和依赖性。此外，官方仍然没有提到更新站点的4.2版本。谢谢，似乎有帮助！但我已经安装了4.2工具包。wizzard试图比用户更智能，但失败惨重的典型案例。
