问题
I am looking for steps to upgrade my current eclipse version(Mars) to latest version(Oxygen) because I have been using Masr for past long time so that contains all the settings, plugins and all the histories so I would like to retain the same and also upgrade to new version.
Is this possible?
Note: It can be any type of eclipse for any kind of development like Java, C/C++, PHP, Javascript and Testers
回答1:
- In Window > Preferences: Install/Update > Available Software Site add following update site (by clicking Add..., entering update site location and clicking OK):
http://download.eclipse.org/releases/oxygen - Help > Check for Updates

There are some package structural changes from Eclipse Neon.

I don't think updating from Update Site will update the eclipse.ini file: you need to fix it.
-startup
plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar
--launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.500.v20170531-1133
However, if you simply want to keep your preferences and your plugin, I suggest you to use Eclipse for that:
In Oxygen.1 (or the updated Eclipse), you can install feature/plugins
- using an existing installation (go to File > Import then select *Install > From Existing Installation)
- using an exported software item (go to File > Import then select *Install > Install Software Items from File)
For the second option, you need to export it first on the previous Eclipse using File > Export > Install > Installed Software Items to File.
Note: the Eclipse directory store little configuration (at least, it store the known workspaces/update site). This link here might be of interest.
