是否可以在一台计算机上安装多个Eclipse？ [英] Is it possible to have multiple Eclipse installs on one computer?

问题描述

是否可以在一台计算机上安装多个Eclipse？为了使自己更清楚，Eclipse会创建任何本地设置文件，其他安装将会自动错误吗？

解决方案

我做Eclipse插件开发，所以我有9个日食安装，从3.2到4.2

我把每个Eclipse放在这样一个单独的目录。

  C：
 eclipse-3.6 RCP 
 eclipse-4.2 Java 
 eclipse-4.2 RCP 
  

我将Eclipse包解压到相应的子目录。

我使用Windows，所以我为Eclipse可执行模块（eclipse.exe）创建一个快捷方式。

我为每个Eclipse实例都有一个单独的工作区。当我想将我的一个工作区升级到更新的Eclipse时，我执行以下操作：

1. 将较新的Eclipse解压缩到eclipse目录。我最近的版本是Eclipse Luna（4.4.2）。




2. 创建一个新的工作区。




3. 仔细地，将一个Java项目从旧工作区复制到新的工作区。测试并确保Java项目中的所有工作正常。




4. 将旧工作区保留至少6个月。 / p>

如果您使用Eclipse插件，则步骤3有所不同。

3. 创建一个新的Eclipse插件。仔细地将Eclipse插件代码从旧的Eclipse插件复制到新的Eclipse插件中。在重建Eclipse插件时进行测试。这看起来很痛苦，这就是为什么我不经常升级我的Eclipse插件。

Is it possible to have multiple Eclipse installs on one computer? To make myself more clear, does Eclipse create any local settings files that other installs would mistake for their own?

解决方案

I do Eclipse plug-in development, so I have 9 Eclipses installed, from 3.2 to 4.2

I put each Eclipse in a separate directory like this.

C:
    eclipse-3.6 RCP
    eclipse-4.2 Java
    eclipse-4.2 RCP

I unzip the Eclipse package to the appropriate sub-directory.

I use Windows, so I create a shortcut for the Eclipse executable modules (eclipse.exe).

24 September 2015 update based on the comments:

I have a separate workspace for each of my Eclipse instances. When I want to upgrade one of my workspaces to a newer Eclipse, I do the following:

1. Unzip the newer Eclipse to a eclipse- directory. My most recent version now is Eclipse Luna (4.4.2).

2. Create a new workspace.

3. Carefully, one Java project at a time, copy the project code from the old workspace to the new workspace. Test and make sure everything in the Java project works.

4. Keep the old workspace as a backup for at least 6 months.

If you work on Eclipse plug-ins, step 3 is a bit different.

3. Create a new Eclipse plug-in. Carefully copy your Eclipse plug-in code from the old Eclipse plug-in to the new Eclipse plug-in. Test as you reconstruct your Eclipse plug-in. This is as painful as it reads, which is why I don't upgrade my Eclipse plug-ins too often.
