How to delete eclipse plugin

How to uninstall plugins in Eclipse 3.4.X or higher

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.

The option to remove the selected Mylyn plugin 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?

The following text is quoted from the Eclipse help docs:

The Uninstall wizard allows you to review and uninstall items in your configuration. This wizard is shown when you select items and press Uninstall. from the Installed Software page. To uninstall software from your system:

Click Help > About and then click Installation Details. to open a dialog showing pages that provide more detail about your installation.

Click the Installed Software tab to see a list of the software items that you have installed into your system.

Select the items that you wish to uninstall.

The Uninstall Details page will show you a list of the items that will be uninstalled. Expanding each item will show what additional items (if any) will be uninstalled as a result of your choice.

If you change your mind about which items should be uninstalled, you may click Back to see a checkmark list of the items you selected before. You may check and uncheck different items in the list, and click Next when you are ready to continue.

Once all of the software is uninstalled successfully, you will be prompted to restart for the Workbench. Click Yes when asked to exit and restart the Workbench for the changes to take effect.

Help->Install New Software at the bottom of dialog there is link What is already installed once you click on that you will get list of installed plugins and Uninstal. button

eclipse 3.5(Galieo) Help>> Install New Software >> Already Installed Plugins >> select Plugins >> Uninstall works charm.

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.

The standard Eclipse distributions come with Myln.

BTW, Eclipser 3.5 completely changes all these screens 🙁

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«.

In eclipse Helios (version 3.6), to uninstall a plugin:

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.

While Help → About Eclipse IDE [or wherever it was in the past or will be in the future] → Installation Details → Installed Software → Uninstall. is the official and preferred way there are features/plugins the latter button of which is disabled.

Remember also that there aren’t only plugins but features too. In my case I wanted to remove Mylyn and Wild Web Developer from a rather fresh Eclipse IDE for Enterprise Java and Web Developers package. I did the following.

After starting Eclipse there were about a dozen «not found» errors in Eclipse’s Error Log view. If you double-click on each of them you can see which dependency plugin JAR(s) haven’t been found.

Note that this applies to a rather fresh Eclipse 2021-03 (4.19.0) installation. It might be different from one – even patch – version to the other.

Keep Eclipse’s Error Log view open for a while. The underlying OSGi activates bundles (plugins) on the fly if they are referenced from an other bundle (plugin) for the first time. And if one isn’t there then.

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.

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

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.

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.

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!

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.

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.

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:

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

Uninstalling and Deleting plug-ins from eclipse

I am uninstalling a plugin named X from eclipse uninstall option. Now to make a clear approach I went to the eclipse plugins directory and delete the plugin jar file from there. Now I am trying to reinstall the same plug-in and eclipse prompts an error saying

An error occurred during the org.eclipse.equinox.internal.p2.engine.phases.CheckTrust phase. session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.CheckTrust, operand=, action=). Error reading signed content. The file «D:\Testing\eclipse-jee-helios-SR1-win32\eclipse\plugins\x_1.1.3.jar» does not exist

Now how to resolve the above issue

I have similar issue. I deleted those plugins related files from eclipse/plugins and eclipse/features directory. The reason why I did that is because I have already uninstalled the plugins from eclipse but the files remain in both directories. I solved it by editing the eclipse/artifact.xml. I search all the artifacts with the id of my plugins and remove them. And I am able to reinstall the plugins again 🙂

You should never delete plugins you installed using the Eclipse installer under Help>Install New Software. Now there is directory used to drop in plugins as jars, which I am assuming you used, if so deleting it would result in the desired behavior assuming you shut down eclipse before hand. If not then you need clean your configuration area. In the future when removing go to Help>Install New Software>Already Installed software, there should be a remove once your there. 🙂

As per eclipse documentation

You should not remove plug-ins from Eclipse. Plug-ins should be installed as features using the Update Manager. The same Update Manager can be used to disable plug-ins by disabling the feature they belong to. Run Help > About Eclipse > Installation Details, select the software you no longer want and click Uninstall. (On Macintosh it is Eclipse > About Eclipse > Installation Details.) In older versions, you might need to Run Help > Software Updates > Manage Configuration. select the feature of interest, and disable it with the task shown in the right window.

When a feature is disabled, all its plug-ins will be disabled also. They are still available on disk, and they can be enabled at any time in the future.

To physically remove the feature and its plug-ins, you will have to manually remove the feature from the eclipse/features directory and its plug-ins from the eclipse/plugins directory. We advise extreme caution here. Remove the wrong ones, and you may have quite some trouble restoring your Eclipse to a stable state. Unless you care a lot about hard disk use, we recommend leaving the plug-ins where they are.

Correct way to remove plugin from Eclipse

Last times, I’m facing problem of removing plugins from Eclipse.

The question is, what are the steps that guarantee correct full removing of plugin and what is better, manual or automatic removing?

Using the menus, open

In the «Installed software» tab click on the software that you wish to uninstall, then click the «Uninstall. » button below.

If you installed the plug-in by dropping into the dropins folder, then just delete it from the dropins folder and restart Eclipse.

See the answer of @Cogentleman for more recent versions of Eclipse.

I would like to propose my solution,that worked for me.

It’s reverting Eclipse and its plugins versions, to the version just before the plugin was installed.

Eclipse Photon user here, found it under the toolbar’s Windows > Preferences > Install/Update > «Uninstall or update» link > Click stuff and hit the «Uninstall» button.

I’m using Eclipse Kepler release. There is no Installation Details or About Eclipse menu item under help. For me, it was Help | Eclipse Marketplace.

I had to click on the «Installed» tab. The plug-in I wanted to remove was listed there, with an «Uninstall» option.

There are few things to keep in mind:

‘Uninstalling‘ a feature, using the steps above, disable the feature or plug-in.

They are still available on disk, and they can be enabled at any time in the future.

Completely removing a Plugin from the system requires a manual process that should be done when Eclipse is not running.

In order to do this, If you are removing a feature you will have to manually remove the files there associated with the feature from the eclipse/features directory and its plug-ins from the eclipse/plugins directory.

If you are removing a plugin you will have to manually remove the files there associated with the plugin from the eclipse/plugins directory.

From the FAQ of Eclipse:

Be very cautious as to which files you delete, and always have a backup of your Eclipse directory. If you remove the wrong files from these directories, you may have quite some trouble restoring your Eclipse to a stable state. Therefore, unless your hard disk storage capacity is extraordinarily limited, it is recommended that you simply leave the physical files in place.

Correct way to remove install plug-in from Eclipse/STS :

Step 1

Step 2

Inspired by sergionni’s answer, I ended up doing the following steps:

In the Previous configurations table, you can select a configuration and see in the Configuration contents exactly which plugins were installed and are included in it.

It’s easy to find the configuration that contains the plugin you want to remove, using the Compare button. This button is enabled when two configurations are selected.

After tracking the configuration that’s responsible for that plugin, select the previous configuration and press the Revert button.

While Help → About Eclipse IDE [or wherever it was in the past or will be in the future] → Installation Details → Installed Software → Uninstall. is the official and preferred way there are features/plugins the latter button of which is disabled.

Remember also that there aren’t only plugins but features too. In my case I wanted to remove Mylyn and Wild Web Developer from a rather fresh Eclipse IDE for Enterprise Java and Web Developers package. I did the following.

After starting Eclipse there were about a dozen «not found» errors in Eclipse’s Error Log view. If you double-click on each of them you can see which dependency plugin JAR(s) haven’t been found.

Note that this applies to a rather fresh Eclipse 2021-03 (4.19.0) installation. It might be different from one – even patch – version to the other.

Keep Eclipse’s Error Log view open for a while. The underlying OSGi activates bundles (plugins) on the fly if they are referenced from an other bundle (plugin) for the first time. And if one isn’t there then.

How to remove old versions of Eclipse plugins?

After update, old Eclipse plugins remain in «plugins» folder (there are also leftovers in «features» folder).

Is there a way to remove those automatically?

I use the following command:

Notes:

This is documented in Equinox/p2/FAQ, see «Why aren’t bundles being removed when their associated feature has been removed?»

The FAQ answer references an Eclipse Community Forum thread «Plug-in jar remains after feature uninstall» (June 2010) as the origin for this recipe.

The recipe is still valid nowadays, with Eclipse 4.8 Photon.

To get rid of the old plugins you have to clear the Installation History. Go to Help | About Eclipse | Installation Details | Installation History and select all the old stuff. Then click delete and restart. Voila. This works with Eclipse Helios (3.6)

I also want to remove old plugins, but still found no answer today, so I wrote a quick and dirty script guess-old-eclipse-plugins.sh to handle old plugins.

This script will scan plugins directory under Eclipse directory. and will generate a remove-old-eclipse-plugins.txt file which can be used to remove old plugins.

This script is tested under Cygwin 1.7.15 on Windows XP.

guess-old-eclipse-plugins.sh

IMPORTANT NOTICE

Before use the generated remove-old-eclipse-plugins.txt file to remove plugins, make sure all the listed plugins in it are REALLY old plugins. Because, this script can’t handle file name contains more than 1 _ characters. For example: JUnit v3 and v4 plugins are 2 different plugins, but the script will treat it as same plugins because these 2 file names use same org.junit_ prefix.

So, use it VERY CAREFULLY, remove the wrong part before use it, or your Eclipse IDE may not work properly.

Sample output

Sample generated script

Removing old plugins is always a hassle. Especially when you upgrade and your Eclipse just doesn’t want to start again and you need to figure it out via the metadata hell of plugins dependencies.

I’ve seen that couple of you tried to fix this via a script.

Eclipse Plugin Cleaner

Well I have created a java based tool (with tests, build by maven & hosted at github, so you are free to fork it) that checks for duplicities of plugins by introspecting manifest files (or file names if the manifest is incomplete or corrupted).

Правильный способ удалить плагин из Eclipse

В прошлый раз я столкнулся с проблемой удаления плагинов из Eclipse.

Вопрос в том, какие шаги гарантируют правильное полное удаление плагина, а что лучше, ручное или автоматическое удаление?

Поделитесь, пожалуйста, своим опытом.

Используя меню, откройте

Если вы установили подключаемый модуль, зайдя в dropins папку, просто удалите его из dropins папки и перезапустите Eclipse.

См. Ответ @Cogentleman для получения более свежих версий Eclipse.

Я хотел бы предложить свое решение, которое сработало для меня.

Он возвращает Eclipse и его версии плагинов к версии непосредственно перед установкой плагина.

Пользователь Eclipse Photon здесь, нашел его на панели инструментов Windows> Настройки> Установить / Обновить> ссылку «Удалить или обновить»> Щелкните материал и нажмите кнопку «Удалить».

Пришлось щелкнуть вкладку «Установлено». Плагин, который я хотел удалить, был указан там с опцией «Удалить».

Следует помнить о нескольких вещах:

« Деинсталлируя » функцию, используя описанные выше действия, отключите функцию или плагин.

Они по- прежнему доступны на диске, и их можно будет включить в любой момент в будущем.

Для полного удаления плагина из системы требуется ручной процесс, который должен выполняться, когда Eclipse не запущен.

Be very cautious as to which files you delete, and always have a backup of your Eclipse directory. If you remove the wrong files from these directories, you may have quite some trouble restoring your Eclipse to a stable state. Therefore, unless your hard disk storage capacity is extraordinarily limited, it is recommended that you simply leave the physical files in place.

Правильный способ удаления подключаемого модуля установки из Eclipse / STS:

Шаг 1

Шаг 2

После отслеживания конфигурации, отвечающей за этот плагин, выберите предыдущую конфигурацию и нажмите Revert кнопку.

Для некоторых плагинов Eclipse Marketplace удаление может не работать. (Пример: SonarLint v5)

Так что постарайтесь,

поиск по названию плагина в «Установленном программном обеспечении»

Выберите название плагина и удалите его

Дополнительная деталь

Чтобы исправить ошибки плагина, после удаления верните старую версию плагина,

Получите URL-адрес плагина из поиска Google и добавьте его (пример: https://eclipse-uc.sonarlint.org )

Выберите и установите более старые версии плагина. Это решит большинство проблем с плагином.
