如何重新安装已安装的 Eclipse 插件？

How Do You Reinstall Installed Eclipse Plugins?

提问by Joe

How do you "remove" or "copy" an eclipse plugin from one eclipse install to another? E.g. I have two installs of eclipse, one of which has a plugin installed that I don't have an installer for nor is it readily available online. Is it possible to get this plugin installed on my other version of eclipse? If so, how?

你如何“删除”或“复制”一个eclipse插件从一个eclipse安装到另一个？例如，我安装了两次 eclipse，其中一次安装了一个插件，但我没有安装程序，也无法在线获取。是否可以在我的其他版本的 eclipse 上安装此插件？如果是这样，如何？

Also, does it matter if my two versions of eclipse are really different versions, i.e. one is 3.4 and the other is 3.3 or 3.2?

另外，如果我的两个版本的 eclipse 是真正不同的版本，即一个是 3.4 而另一个是 3.3 或 3.2，这是否重要？

As mentioned in my answer to your last question, and since (again) the chosen answer is very poor on the specifics, a plugin lives in:

正如我在对您最后一个问题的回答中所提到的，并且由于（再次）所选答案在细节上非常差，因此插件位于：

• for eclipse previous to 3.4 (3.2, 3.3)

  • eclipse/plugins and eclipse/features

  • any other directory provided you define a link by creating a foo.linkfile inside the linksdirectory of an eclipse installation (you might have to create the [eclipse]\linksdirectory) containing:

    path=C:/eclipse/extensions/foobar

• 对于 3.4 (3.2, 3.3) 之前的 eclipse

  • eclipse/plugins 和 eclipse/features

  • 通过foo.link在Eclipse 安装的链接目录中创建一个文件来定义链接的任何其他目录（您可能必须创建[eclipse]\links目录），其中包含：

    路径=C:/eclipse/extensions/foobar

With references the foobar plugins, with the following subdirectories:

引用 foobar 插件，具有以下子目录：

C:/eclipse/extensions/foobar/eclipse/plugins
C:/eclipse/extensions/foobar/eclipse/features

• for eclipse3.4 and 3.5, with p2 mechanism:
  • by putting your plugin in the dropins directory(like dropins/foobar/eclipse/pluginsand dropins/foobar/eclipse/features, or foobar.zip, with the zip containing eclipse/pluginsand eclipse/features)

• 对于 eclipse3.4 和 3.5，使用 p2 机制：
  • 通过将您的插件放在dropins 目录中（例如dropins/foobar/eclipse/pluginsanddropins/foobar/eclipse/features或 foobar.zip，其中 zip 包含eclipse/plugins和eclipse/features）

So you should look for a plugin in those directories, and copy them into into the appropriate plugin directory for completing the installation.

因此，您应该在这些目录中查找插件，并将它们复制到相应的插件目录中以完成安装。

EDIT: just adding with what eclipse version i'm working: 3.5 galileo

编辑：只需添加我正在使用的 Eclipse 版本：3.5 galileo

I managed to uninstall using the "Install New Software" option (kind of bad-name to reach an uninstallation instance).

我设法使用“安装新软件”选项卸载（到达卸载实例的坏名称）。

You can check this images:

Another way is:

另一种方式是：

Help->About Eclipse->Installation Details

帮助->关于Eclipse->安装详情

And there select the plugin you want to uninstall.

然后选择要卸载的插件。

For more recent versions of Eclipse, there is a much more simple solution: File -> Import -> Install -> From existing installation. Select your features from that second installation and you are done.

对于较新版本的 Eclipse，有一个更简单的解决方案：File -> Import -> Install -> From existing installation。从第二个安装中选择您的功能，您就完成了。

You could copy the relevant folders and jars from the source installation's plugins/and features/folders to the target install and then restart the target Eclipse with the -cleanparameter.

您可以将源安装plugins/和features/文件夹中的相关文件夹和 jar 复制到目标安装，然后使用-clean参数重新启动目标 Eclipse 。

If the plugin has an update site you can copy its url to the new install and run update.

如果插件有更新站点，您可以将其 url 复制到新安装并运行更新。

回答by Jan Jungnickel

Yes, you can do this easily by copying the corresponding directory (or jar) from the source eclipse install plugins/ or/and features/ directory to the target eclipse install plugin/ or/and features/ directory.

是的，您可以通过将相应的目录（或 jar）从源 eclipse install plugins/ 或/和 features/ 目录复制到目标 eclipse install plugin/ 或/和 features/ 目录来轻松完成此操作。

Depending on the Plugin you may encounter compatibility issues when source and target versions differ. Some Plugins work with a braod line of eclipse versions, some require a distinct version.

当源版本和目标版本不同时，您可能会遇到兼容性问题，具体取决于插件。一些插件适用于一系列 eclipse 版本，有些需要不同的版本。

Also, a general hint: Don't be vague, be more specific. Sometimes there are known issues with setups, versions and the like. Being specific can potentially help identify a complex problem.

另外，一般提示：不要含糊其辞，要更具体。有时，设置、版本等存在已知问题。具体可能有助于识别复杂的问题。
