最简单的方法来升级eclipse 3.7到4.2（Juno） [英] Easiest way to upgrade eclipse 3.7 to 4.2 (Juno)

问题描述

所以，因为Eclipse juno是基于4.2而不是3.7，那么升级到最简单的方法是什么呢？没有安装一个juno的单独的副本，而是从3.7中重新安装我现有的所有插件呢？

So since Eclipse juno is based on 4.2 instead of 3.7, what is the easiest way to upgrade to it, short of installing a separate copy of juno and re-installing all my existing plugins from 3.7 into it?

eclipse.org上提到的似乎并不是一个简单的升级路径。

There doesnt seem to be a straightforward upgrade path mentioned on eclipse.org.

推荐答案

Eclipse几乎不能从3.7.1更新到3.7.2，从不会从3.7到4.2。

Eclipse can barely update from 3.7.1 to 3.7.2, never mind from 3.7 to 4.2.

你正在把你的开发环境的生命放在你手中您尝试对现有Eclipse开发环境进行大量升级。我不知道你，但我的开发环境对于升级风险来说太重要了。

You're taking the life of your development environment in your hands if you try to make that much of an upgrade to an existing Eclipse development environment. I don't know about you, but my development environment is too important to risk upgrading.

始终创建一个新的Eclipse目录和新的Eclipse当您要更改开发环境时，工作空间。

Always create a new Eclipse directory and new Eclipse workspaces when you want to change your development environment.

将Eclipse 4.2解压缩到新目录，并一次添加一个插件。您可以使用Bananeweizen的方法来复制Eclipse 3.7插件，也可以手动添加。看看您使用的插件是否已升级为Eclipse 4.2可能是个好主意。

Unzip Eclipse 4.2 to a new directory, and add your plug-ins one at a time. You can use Bananeweizen's method to copy the Eclipse 3.7 plug-ins, or you can add them manually. It's probably a good idea to see if the plug-ins you use have been upgraded for Eclipse 4.2.

创建一个新的Eclipse 4.2工作区，并将您的项目代码从Eclipse 3.7工作区。如果以后发现问题，您可以回到Eclipse 3.7和Eclipse 3.7工作区。

Create a new Eclipse 4.2 workspace, and copy your project code from your Eclipse 3.7 workspace. If you discover a problem later, you can fall back to Eclipse 3.7 and your Eclipse 3.7 workspaces.

当您使用Eclipse 4.2环境时，将其压缩并保留zip文件，以便在Eclipse损坏的情况下还原Eclipse 4.2环境。

When you have an Eclipse 4.2 environment that works, zip it back up and keep the zip file so you can restore your Eclipse 4.2 environment in the event your Eclipse gets corrupted.

从来没有想过改变你的工作环境。
