Google Plugin for Eclipse Luna?
提问by ???v?т?
I have installed Eclipse Luna 4.4-M6. I tried installing the Google Pluginfor Eclipse 4.3 (Kepler), but Eclipse would not allow me to install it.
我已经安装了 Eclipse Luna 4.4-M6。我尝试为 Eclipse 4.3 (Kepler)安装Google 插件，但 Eclipse 不允许我安装它。
Is there some way to force it to install (e.g. by downloading it and editing some manifest or other)? Or would this be futile due to breaking changes between 4.3 and 4.4?
有没有办法强制安装它（例如通过下载它并编辑一些清单或其他）？或者这会因为 4.3 和 4.4 之间的重大变化而徒劳无功？

It turns out there isa way to alter the manifests to allow the Google Plugin for Kepler to install in Eclipse Luna. Contributor Ze Kritteron Google Groups has written an Apache Ant build.xmlfile that performs the necessary work, original hereand reproduced below.
原来有是一种方法来改变体现，让谷歌插件开普勒在Eclipse月神安装。Google Groups 上的贡献者Ze Kritter编写了一个 Apache Antbuild.xml文件来执行必要的工作，这里是原创并在下面复制。
It worked beautifully for me. I have successfully run this script and installed the plugin into Luna, and - at least for GWT - it seems to work as usual.
它对我来说效果很好。我已经成功地运行了这个脚本并将插件安装到 Luna 中，并且 - 至少对于 GWT - 它似乎像往常一样工作。
According to the discussion threadon Google Groups there are some incompatibilities with the Maven plugin (I personally don't use Maven) and a new and suitably well-tested Google plugin will be coming out shortly (late July 2014).
根据Google Groups 上的讨论主题，Maven 插件存在一些不兼容问题（我个人不使用 Maven），并且不久（2014 年 7 月下旬）将推出一个经过适当测试的新 Google 插件。

I'll add the words Eclipse Marshere, so this solution can be found by searching and potentially adapted for the June 2015 release of Eclipse.
我将在此处添加Eclipse Mars字样，因此可以通过搜索找到该解决方案，并可能适用于 2015 年 6 月发布的 Eclipse。

According to the Google Plugin for Eclipse community forum, we might be able to expect a new plugin with Luna support by mid-July.
根据 Google Plugin for Eclipse 社区论坛，我们可能会在 7 月中旬之前期待一个支持 Luna 的新插件。

This seems to be recently resolved.
这似乎是最近解决的。
I didn't find the plugin in the Marketplace as of writing this, but there's an update site: https://dl.google.com/eclipse/plugin/4.4
在撰写本文时，我没有在 Marketplace 中找到该插件，但有一个更新站点：https: //dl.google.com/eclipse/plugin/4.4
