Java 如何在 Eclipse 3.4.X 或更高版本中卸载插件

How to uninstall plugins in Eclipse 3.4.X or higher

提问by Dónal

The GUI for managing plugins in Eclipse got a bit of an overhaul in version 3.4.0. This GUI is accessed via the "Software Updates..." option in the Help menu. This displays the following dialog:

用于在 Eclipse 中管理插件的 GUI 在 3.4.0 版中进行了一些大修。此 GUI 可通过“帮助”菜单中的“软件更新...”选项访问。这将显示以下对话框：

alt text http://www.iol.ie/~murtaghd/img/eclipse-2.jpgNotice that the option to remove the selected plugin (Mylyn) is greyed out. In fact, this is true of virtually every installed plugin. I know that the Mylyn plugins are optional, so why amn't I provided with an option to remove them?

alt text http://www.iol.ie/~murtaghd/img/eclipse-2.jpg请注意，删除所选插件 (Mylyn) 的选项是灰色的。事实上，几乎所有已安装的插件都是如此。我知道 Mylyn 插件是可选的，那么为什么我没有提供删除它们的选项呢？

Thanks, Don

I'm running (a relatively fresh copy of) 3.4.1. I was able to select the same plug-in shown in your screen shot (Mylyn Bridge: Java Development) to get an enabled "Uninstall..." button. I'd suggest getting the latest updates and trying again.

我正在运行（一个相对较新的副本）3.4.1。我能够选择屏幕截图（Mylyn Bridge：Java Development）中显示的相同插件来启用“卸载...”按钮。我建议获取最新的更新并重试。

There are distributions of Eclipse that come packaged with certain plugins that can't be mix-and-matched. That is the case with Mylyn, that went from a student's thesis project to an integral part of Eclipse. If you want to actually get rid of Mylyn, you may want to install Eclipse classic instead of the distribution you have, and then install the stuff you need.

有一些 Eclipse 发行版打包了某些不能混合搭配的插件。Mylyn 就是这种情况，它从学生的论文项目变成了 Eclipse 的一个组成部分。如果您想真正摆脱 Mylyn，您可能需要安装 Eclipse classic 而不是您拥有的发行版，然后安装您需要的东西。

The standard Eclipse distributions come with Myln.

Myln 提供了标准的 Eclipse 发行版。

BTW, Eclipser 3.5 completely changes all these screens :(

顺便说一句，Eclipser 3.5 完全改变了所有这些屏幕:(

It sure looks like there's no way to do this.

看起来确实没有办法做到这一点。

I just had exactly this problem with a fresh download of the Eclipse Java IDE (Ganymede SR2). I didn't want Mylyn, but I didn't want "Eclipse Classic", either, because the download was twice the size, I presume because it includes source.

我刚刚在全新下载 Eclipse Java IDE (Ganymede SR2) 时遇到了这个问题。我不想要 Mylyn，但我也不想要“Eclipse Classic”，因为下载的大小是它的两倍，我猜是因为它包含源代码。

The apparent solution was to update everything and restart Eclipse, after which the "Uninstall..." button became enabled for the Mylyn plugins. Unfortunately, this only uninstalled the most recent, updated version (3.0.11 IIRC), reverting to the un-uninstallable 3.0.5.

明显的解决方案是更新所有内容并重新启动 Eclipse，之后“卸载...”按钮为 Mylyn 插件启用。不幸的是，这只卸载了最新的更新版本 (3.0.11 IIRC)，恢复到不可卸载的 3.0.5。

I just don't know what the hell these Eclipse developers are thinking! Removing plug-ins from Eclipse became a pain in the ass since Helios!

我只是不知道这些 Eclipse 开发人员到底在想什么！自 Helios 以来，从 Eclipse 中删除插件变得非常痛苦！

I hear you pal... I just went through the whole day trying to figure out as no one seems to give an straight answer like "do this, that, done." Man I'd rather be programming instead....

我听到你的朋友......我花了一整天试图弄清楚，因为似乎没有人给出直接的答案，例如“做这个，那个，完成。” 伙计，我宁愿编程....

Found, in the middle of my evening that it is possible to uninstall pretty much everything. The issue is that the damn thing is hidden in the "HELP->ABOUT". Who would guess after going over and over through the "Help->Install New Software" or "Help->Check for updates" and never finding anything like "remove" or "reinstall" or "force reinstall". Seriouly, I'd rather go back to 1990 when we had Microsoft, Borland and Watcom.. you picked your platform and you'd be with 1/3 of the world of developers with you.. ok, perhaps Watcom didn't hit that mark but you get the point.

发现，在我傍晚时分，几乎可以卸载所有内容。问题是该死的东西隐藏在“帮助->关于”中。谁会在一遍遍地通过“帮助->安装新软件”或“帮助->检查更新”而没有找到诸如“删除”或“重新安装”或“强制重新安装”之类的东西后猜测。说真的，我宁愿回到 1990 年，那时我们有 Microsoft、Borland 和 Watcom。你选择了你的平台，你就会和世界上 1/3 的开发人员在一起......好吧，也许 Watcom 没有成功那个标记，但你明白了。

So... to uninstall any plugin from Eclipse Helios (Service Release 1) or Springsource 3.5.2 (or 3.6.1 I 'm using), do this:

所以...要从 Eclipse Helios（Service Release 1）或 Springsource 3.5.2（或我正在使用的 3.6.1）卸载任何插件，请执行以下操作：

1. close all your projects (just to be on the safe side);
2. Hit menu "HELP-->ABOUT" (yeah.. help, about);
3. Hit "Installation Details" button and you get the list with all plugins;
4. Click on the one you want to remove; hit uninstall;
5. If want to remove more than one, just apply the change without restart;
6. Goto to 4) as needed
7. Finally, restart Eclipse and reinstall what you need !

1. 关闭所有项目（只是为了安全起见）；
2. 点击菜单“帮助-->关于”（是的..帮助，关于）；
3. 点击“安装详细信息”按钮，您将获得所有插件的列表；
4. 单击要删除的那个；点击卸载；
5. 如果要删除多个，只需应用更改，无需重新启动；
6. 根据需要转到 4)
7. 最后，重新启动 Eclipse 并重新安装您需要的东西！

It was hard to find, but it worked very well for me.

很难找到，但对我来说效果很好。

In Eclipse 3.6 Helios, the interface has changed again. Go to "About Eclipse", and then click the "Installation Details" button in the about box.

在 Eclipse 3.6 Helios 中，界面再次发生了变化。转到“关于 Eclipse”，然后单击关于框中的“安装详细信息”按钮。

If you are using Windows, make sure you are running Eclipse as administrator. Without administrator privileges, some options may be grayed-out in "Installed Software".

如果您使用的是 Windows，请确保您以管理员身份运行 Eclipse 。如果没有管理员权限，“已安装的软件”中的某些选项可能会变灰。
