Eclipse Luna的谷歌插件？

Question

我已经安装了Eclipse Luna 4.4-M6。我尝试为Eclipse 4.3（开普勒）安装谷歌插件，但Eclipse不允许我安装它。

是否有一些方法可以强制安装它（例如通过下载它并编辑一些清单或其他）？或者由于4.3和4.4之间的中断更改，这是徒劳的？

Answer 1

这似乎是最近才解决的。

在撰写本文时，我没有在市场上找到该插件，但有一个更新网站：https://dl.google.com/eclipse/plugin/4.4

您可以在以下网站阅读更多信息：https://developers.google.com/eclipse/docs/install-eclipse-4.4

事实证明，有一种方法可以改变清单，允许开普勒的谷歌插件html" target="_blank">安装在Eclipse Luna中。Google Groups上的贡献者Ze Kritter编写了一个Apache Ant构建。执行必要工作的xml文件，此处为原件，下面复制。

它对我来说工作得很好。我已经成功运行了这个脚本并将插件安装到Luna中，并且——至少对于GWT来说——它似乎像往常一样工作。

根据谷歌群组上的讨论线索，Maven插件与Maven存在一些不兼容之处（我个人不使用Maven），一个新的、经过适当测试的谷歌插件不久将推出（2014年7月底）。

我将在此处添加单词Eclipse Mars，因此可以通过搜索找到此解决方案，并可能针对2015年6月发布的Eclipse进行调整。

根据Eclipse社区论坛的Google插件，我们可能会在7月中旬看到一个支持Luna的新插件。
