Had some strange errors, described here: lost in deployment: session.getAttribute() returns NULL in some Tomcat configurations and been advised to remove the SysDeo plugin.
Googled on how to remove plugins in Eclipse 3.6, found the plugin in Eclipse Installation Details, still looking for some "uninstall/remove" button. Or should I just remove the files from some of the eclipse sub-folders (contrary to what is written in Eclipse tutorials) and it'll work?
Thanks!
Help->About>Installation details->Installed software tab
Click on the software that you want to unistall and the "uninstall" button becames enabled. Click that button to uninstall the software.
EDIT: In your comment you say that you installed the plugin by dropping it in the "dropins" folder. Well, according to this, the way to uninstall it would be to just delete it from the "dropins" folder and restart Eclipse.

Every question dealing with uninstalling/disabling plugins for Eclipse Juno mentions an Uninstall button but I simply can't find it and Eclipse's help for Juno is sadly no help.
Has this ability been eliminated or omitted or is it in some place different for Juno?
The Uninstall... button is available from the About Eclipse dialog. From that dialog click Installation Details and it's under the Installed Software tab. This typically is only available for features, not plugins. If you can find the appropriate feature that contains the plugins you want to eliminate, that should do the trick for you.
If you are unsure of the feature containing the plugin, you can attempt to go the Installation History tab in the Installation Details window and try to Revert to a previous version of Eclipse that didn't have the plugins.
Finally, you can always manually go into your Eclipse installation folder under the plugins directory and remove them manually. This will sometimes require that you run eclipse -clean from your command line/terminal to truly get rid of the plugin. This is probably the most error prone approach as you could cause problems with features/plugins that may depend on the removed plugins.
I want to install my pugine in eclipse without opening the eclipse. i have copied my plugin in plugin folder but by using this way i am not able to Uninstall plugin from eclise. When i am trying to uninstall plugin from "Eclipse Installation Detail" the Uninstall button is disable. i dont understand what is the proper way to install plugin without opening the eclipse. if is there any proper way then let me know.
Thanks
In latest versions of Eclipse (since Eclipse 3.4), a new provisioning mechanism appeared. You should never make any modification yourself in the Eclipse filesystem. You have to use p2 for manipulating your Eclipse installation.
Refer to the following links, for a first step in this install mechanism: http://wiki.eclipse.org/Equinox_p2_Getting_Started
To manipulate things without launching the Eclipse itself:
http://wiki.eclipse.org/Equinox_p2_director_application
If you manualy copy the plug-in in your Eclipse folder, then you are responsible for removing it. Since you didn't go through the Eclipse install mechanism, Eclipse is lacking the metadata needed to uninstall it. It basically says: "I see it is there, but I don't know how it got there, so better not remove it."

I have Eclipse Galileo (for Java EE Developers) installed, and I'm now trying to get the m2eclipse Maven plugin installed as well.
I follow the basic steps described at http://m2eclipse.sonatype.org/installing-m2eclipse.html, and it seems to be installing just fine. However, after restarting Eclipse after the install it doesn't seem to be anywhere. I should for instance have the ability to create a new maven project, but when the new-project wizard opens, there is no folder for Maven (I also cannot find any reference to it in the context menus of the existing projects I have).
When I click at Help > About Eclipse > Installation Details, I find "Maven Integration for Eclipse (Required)" in the tab "Installed Software", yet another thing pointing towards a successful installation (but I can't find it under the "Plug-ins" tab, should it be there too?)...
I feel like I'm just missing something very obvious, but right now I just don't see it...
I managed to find the answer to this myself:
I had put the Eclipse installation folder under c:\Program Files\, but when I moved it directly under c:\ instead, the plug-in installation worked just as it should. I assume that is because Eclipse wasn't allowed to write to its own installation folder (but I didn't get the usual question from Windows that something was trying to access Program Files either...).
In one way I feel like I should be a bit ashamed that I didn't think of this before. On the other hand though, there could have been some reasonable error message stating that something failed during the plug-in installation...
Well, I hope this at least helps somebody else as well :)
Did you check the m2eclipse installation requirements?
In particular, you need WTP.
"Maven integration for Eclipse" (core feature) and optional "Maven POM Editor" feature depend on the "Eclipse XML Editors and Tools" feature from WST
"Maven integration for WTP" feature provides Maven project configuration for WTP
Did you have a previous version of m2eclipse installed? Did you uninstall it before to install the latest version? Just in case, does the following note applies to you?
Note about 0.9.8 Workspace Incompatibility: If you are using
m2eclipse 0.10.0 with a workspace that
contains projects created under
m2eclipse 0.9.8, you must remove the
workspaceState.ser file. The
workspaceState.ser file is located
within the workspace directory in
$workspacedir/.metadata/.plugins/org.maven.ide.eclipse/workspaceState.ser.
If you remove this file, m2eclipse
0.10.0 will regenerate it as needed.
In my case, uninstalling the previous m2eclipse version didn't work and I had to start with a fresh Eclipse install (maybe try this also).
Regarding the plugin tab, this is what I have (to confirm that you should definitely find something):

Note that I also installed some extras from m2eclipse Extras Update Site: http://m2eclipse.sonatype.org/sites/m2e-extras
I was able to solve this problem by going into Program Files, right click on the eclipse.exe file and select "Run as administrator". When I restarted Eclipse it said I had no plugins installs so I reinstalled and my problems were solved.
PROBLEM SOLVED
I had this same problem and I used the following software site:
["M2Eclipse - http://download.eclipse.org/technology/m2e/releases/1.0] (without square brackets) to download the M2Eclipse plugin in Eclipse 3.7.0 (Indigo). For more information refer this.
To solve the problem of 'not getting Maven plugin running in eclipse' , it can be solved by altering admin rights to the .m2 folder . Right click on .m2 folder and go to network sharing. give all rights to all users. Restart eclipse and maven options will start to appear in Eclipse.
I don't need m2eclipse to work properly, I just need to remove m2eclipse for now and let eclipse behave normally. how do i do this?
Two solutions:
Remove the plugin through the list of installed plugins
(the illustrations are from the blog post "Install Eclipse UI Form Editor" written by Albert ATTARD):
The "about eclipse" menu will give you access to the list of installed Software:
You can click on the right application (m2eclipse for you, Jiglo in this example), and click uninstall, and restart eclipse.
A safer solution would be first to install a new fresh copy of Eclipse, and add your existing plugins (except m2eclipse): if that fails, you still have your previous Eclipse installation untouched.
after doing what VonC suggested, goto the directory eclipse\plugins and search anything with m2e and remove it from the directory
also do the same for the eclipse\features directory.
then you won't be seeing any of the m2e things again.
i would have used m2e if it had a command line feature similar to
"mvn eclipse:clean" and "mvn eclipse:eclipse"
sadly their both incompatible with each other..
right now all i needed are those two command lines to get me up and running with eclipse just to browse and edit the code, etc..
I am new to Eclipse so I am having a hard time troubleshooting this problem. I have a new installation of Eclipse Java EE - Galileo on Windows, and I am unable to see any changes made in the IDE after installing plugins. I have verified that the plugins are installed via installation details, but see no changes made.
For example, after installing the maven integration plugin m2eclipse I go to File->New->Project ... and I have no option for maven. After installing the QuickRex plugin I have no view for it etc.
I have tried re-installing the plugins, re-installing Eclipse, and starting Eclipse with the -clean option, but nothing has resolved the issue.
Any ideas? Thanks!
Ok. This is just a wild guess but could you start over with a fresh install and make sure that you uncheck the option Contact all update sites during install to find required software as shown below:

I faced a similar problem (on another platform than yours), some updates were "disabling" all my plugins. Not checking this option allowed me to work around this issue.
Follow-up: You'll need to install that Zest stuff manually from the GEF update site:
