Cannot upgrade/un-install m2eclipse plugin in Eclipse - eclipse

I have Eclipse 3.6 with m2eclipse (Maven's plugin for Eclipse) 1.1, it works.
And now I want to try m2eclipse version 1.4, I upgrade it directly and find I cannot see Maven in any menu. Then I try to uninstall and re-install it but I always get this message and Eclipse doesn't install anything.
Your original request has been modified.
"m2e - Maven Integration for Eclipse" is already present because other installed
software requires it. It will be added to the installed software list.
Finally, I try to search all files contain "m2e" and delete them from Eclipse's directory, but still get the same message, any suggestion to un-install m2eclipse?
ps: I use Eclipse Help > About eclipse > Installation details to un-install and restart to make sure m2e is not in Eclipse before re-install. I also use -clean parameter but still the same.

You can remove the m2e plugin in Eclipse Help > About eclipse > Installation details. You should find all the m2e to uninstall.
Edit :
You could also reload eclipse with the -clean option so any cached data used by the OSGi framework and eclipse runtime will be wiped clean

Maven found missing in Eclipse IDE (Mars) after installing m2e-egit

unable to create a maven project after installing the m2e-egit plugin; Obviously I don't see the maven option under Eclipse > Window > preferences
Tool used:
Eclipse Java EE IDE for Web Developers.
Version: Mars Release (4.5.0)
Try this :
Firstly, for Maven:
Eclipse > Help > Install new software and add http://download.eclipse.org/technology/m2e/releases.
Secondly, for m2e-egit:
Eclipse > Help > Install new software and add
https://repository.takari.io/content/sites/m2e.extras/m2eclipse-egit/0.14.0/N/LATEST/.
Because the version of m2e-egit in the Marketplace is outdated
Now restart eclipse.
It perfectly worked for me (Mars Version).
I had this same issue with m2eclipse-scala. I tracked the issue down to what seems to be multiple installs of the m2e plugin, one explicit and one implicit. This plugin gets installed by m2eclipse-scala if it's not already there (perhaps similarly to how m2e-egit operates). The base version of Eclipse that I'm using does NOT show m2e installed under Window > Installation Details, but all of the Maven buttons and toolbars are already present, and explicitly installing m2e makes them disappear.

Maven for Eclipse 1.5.0 plugin cannot be installed under Kepler

I downloaded Eclipse Kepler and tried to install M2Eclipse from its update site.
After selecting Maven Integration for Eclipse, I clicked Next and got the following error:
Missing requirement: Maven Integration for Eclipse 1.5.0.20140606-0033 (org.eclipse.m2e.core 1.5.0.20140606-0033) requires 'bundle com.google.guava [14.0.1,16.0.0)' but it could not be found
So I searched through the internet to find out how to install the Guava Eclipse plugin. Some say it's from the Eclipse marketplace, but it cannot be downloaded. I downloaded the binary and tried to copy it to Eclipse's plugin directory. Still the same result.
cp ~/Downloads/guava-16.0.1.jar /Applications/eclipse/plugins/com.google.guava_16.0.1.v1234.jar
How do I install the m2e plugin for Kepler?
m2e 1.5.0 requires Eclipse Luna. It will not work with Kepler or Indigo. (thanks to #HDave for the link)
So you have to use an older version of m2e under Kepler.
During installation, uncheck "Show only the latest versions of available software". Then only check the 1.4.1 version or lower version in the candidate list. It doesn't require the Guava dependency.
Make sure you have the Luna repository in "Available Software Sites".
You can add it in : Help -> Install New Software...
Then in the "Work with" input, you type http://download.eclipse.org/releases/luna/ and press enter.
After that, you should be able to install m2e with http://download.eclipse.org/technology/m2e/releases/
You can find Guava 15 on Orbit project - "repository of bundled versions of third party libraries that are approved for use in one or more Eclipse projects". You can also directly add the Orbit project update site to your kepler installation and you'll be able to update m2e
What has helped me for Juno release is adding http://download.eclipse.org/technology/m2e/releases/1.3/ as plugin update site. The version of Maven for Eclipse was 1.3 instead of 1.5 but, for me, this differrence was less principal than the absence of extra dependencies and extra update sites, especially that of the newer version of IDE itself.
Do you necessarily need version 1.5 or 1.3 also should be good?
STEPS TO INSTALL MAVEN (in Eclipse):
Maven Eclipse plugin installation step by step:
Open Eclipse IDE
Click Help -> Install New Software...
Uncheck "Show only the latest versions of available software"
Click Add button at top right corner
At pop up: fill up Name as "M2Eclipse" and Location as"http://download.eclipse.org/technology/m2e/releases"
Check only one 1.4.1 Version.
Now click OK After that installation would be started.
http://download.eclipse.org/technology/m2e/releases
This URL does not work.
http://download.eclipse.org/technology/m2e/releases/1.3/
This one can work.

Installation of FindBugs plugin with Eclipse IDE for Java EE Developers

I'm struggling to get the Eclipse FindBugs plugin to work and am sure there's a schoolboy error being made somewhere.
I extracted the file findbugs-2.0.2-rc2.zip to a local folder C:\Program Files\findbugs-2.0.2-rc2 and running findbugs.bat, FindBugs works fine running it over a local Java (Eclipse) project.
I added the FindBugs update site, it found "FindBugs Feature, 2.0.1.20120712" and installed it. Restarting, right-clicking on an open Java Project doesn't display the "FindBugs" option (that this video shows).
I looked in Window > Preferences to try to find a way to inform the plugin of the local FindBugs installation (in Program Files), but couldn't find anything.
Uninstalling "FindBug Feature", I tried extracting the FindBugs Eclipse plugin zip file into Eclipse's plugins folder, but after a restart, saw no difference.
Help > About Eclipse > Installation Details > Installed Software lists "FindBugs Feature 2.0.1.20120712".
Can anyone please offer a pointer on where I'm going wrong here? Thanks!
Windows 7, Eclipse IDE for Java EE Developers Juno SR1, JDK 1.7.0_09, FindBugs 2.0.2-rc2
As suggested above, problem is likely caused by not having appropriate write access to the C:\Program Files\Eclipse\plugins folder.
Solution:
Close Eclipse. Restart Eclipse as Administrator (right click - Run as Administrator). Reinstall plugin. Restart Eclipse.
It looks like the Findbugs plugin wasn't installed properly and/or disabled by Eclipse. There can be several causes.
Multiple versions of the same plugin. To make sure this isn't the case, remove all Findbugs versions (installed manually and via the marketplace), and reinstall one (preferably via the marketplace). Watch for any warnings during installation.
There is a (dependency) conflict with another plugin. However, if this is the case I think Eclipse will warn in the log which other plugin is the cause of the conflict.
Rights problem. Make sure you have write permissions in the main Eclipse folder and all it's child folders.
I remember reading somewhere that installing Eclipse under the C:\Program Files\ in Windows can also be causing problems. Try moving Eclipse to a different folder, e.g. C:\Eclipse
Hi I also faced the similar problem but from my own experience i can suggest you the solution :-
Plz ensure that you are using eclipse version 3.6 or higher. findbugs 2.0 is not compatible with Eclipse 3.5(Eclipse Galileo).
1) Plz extract the findbugs zip file into eclipse folder(wher your eclipse is installed). This will automatically move findbug plugins into eclipse plugins folder. Restart the eclipse and you will find findbugs option on right clicking on project.
2) if 1 step does not work plz remove all the findbug jars for the eclipse plugins folder and place the complete folder into the eclipse dropins folder. Restart the eclipse and you will see the difference.
You can follow these step's to make findbugs work in your eclipse.
1.Install FireBug plugin from marketplace.
Help->Eclipse Marketplace ->then search for FindBugs
2.Configure FindBug for your project
using Maven Without Maven
This worked fine for me using eclipse juno.

M2e is not visible in Eclipse

I'm trying to install m2e plugin to enable maven integration but it looks like plugin is not installed:
What I do:
Maven is already installed in the system and 'mvn --version' works
Help -> Install New Software -> Indigo->General Purpose Tools - m2e
Eclipse restart of course
There is no mention of Maven in eclipse. Not in Window->Preferences, not when creating new project. Nowhere.
Tried different plugin repositories, tried Eclipse Marketplace - nada.
When running Eclipse I get these errors:
org.eclipse.m2e.logback.configuration: SLF4J logger factory is not an instance of LoggerContext: org.slf4j.impl.SimpleLoggerFactory
2 [org.eclipse.jdt.internal.ui.text.JavaReconciler] INFO org.mortbay.log - Logging to org.slf4j.impl.SimpleLogger(org.mortbay.log) via org.mortbay.log.Slf4jLog
Not sure what to do at this point.
Would be grateful for any help!

I don't recall what it is called in Indigo. I recently updated to Juno and imported my plugins with no issue. Below is a full list of plugins that I have installed. I'd recommend you uninstall what you have, then search for "Maven Integration". Install that and any other related plugins you will need (i.e. SCM clients).
It is builtin with Indingo, no !?
(Or maybe Indigo WTP)
I am quite sure because I had to re-install Indigo WTP several times

Problem installing Maven plugin (m2eclipse) in Eclipse (Galileo)

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):
alt text http://www.imagebanana.com/img/84h6mw8z/screenshot_008.png
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.
