Conflict in Eclipse Mars with Maven and SVN?

I've been using Eclipse for programming and testing Storm just fine, however, I created an SVN account, where I commit the project, and for that, I needed the SVN plugin for Eclipse. It worked, but after that, i get this message on a popup error window when I try to launch:
Referenced classpath provider does not exist:
org.eclipse.m2e.launchconfig.classpathProvider
I realised that in the "configure" menu, the option "convert to maven project" (right click on project) disappeared. The "runAs" options for the java topology doesn't run with this error, and the "pom.xml" cannot be run as maven.
Possible fix tried:
I tried to reinstall all maven builders to Eclipse(it doesn't let me to unninstall).
I tried to rebuild config by:
mvn eclipse:clean eclipse:eclipse
None of this worked, my Eclipse version is:
Eclipse Java EE IDE for Web Developers.
Version: Mars.1 Release (4.5.1)
Build id: 20150924-1200Eclipse Java EE IDE for Web Developers.
On Ubuntu Gnome 14.04.
As I said, it was running perfect until I installed SVN plugin.
EDIT
I realised that I have installed two plugins of m2e:
Maven integration for Eclipse (Luna and newer)1.5
Maven integration for Eclipse (Luna)1.5.0
Both in marketplace, but I have no way to uninstall them, it says:
[plugin] cannot be fully uninstalled because other installed software requires it. The parts that are not required will be uninstalled.
EDIT 2
In the "Installation History" within the "Help>Installation details" menu, I saw that "Maven integration for Eclipse (Luna)1.5.0" was installed by (or with) SVN plugin, so I think the problem is there, nevertheless, I can't uninstall it as I said in my first "EDIT".
If anyone has a clue about what is happening, please, help me.
Thanks in advance!

We use Subclipse in Eclipse (Kepler and Mars) without problems (Did you install Subclipse or Subversive?).
To check out projects as Maven projects, you should install a m2e connector. Subversive has one in the "Discovery" catalog while for Subclipse there is a separate update site.
If your eclipse plugin configuration is somehow broken, I would start again with a virgin eclipse (Mars.1, Mars.2 or Neon) which already contains m2e in version 1.6 or 1.7. Then you can install Subclipse or Subversive and try again.

Workaround proposal: simply don't deal with SVN within eclipse!
Instead, you can use "git svn" on ubuntu.
Meaning: with git svn you can create a local git repository, that allows you to commit/fetch to a remote SVN server. But to your eclipse ... that repository looks a common of garden GIT repository.
In other words: using that tool, you can still connect to SVN (although I don't understand why anybody would want to do that in 2016); but you have all the features of git available to you as well (including full support within eclipse; without installing any additional plugins).

eclipse: No "Maven" entry for Windows / Preferences

I had eclipse Juno running; I decided to upgrade to eclipse Kepler. I only had Java 1.6, so I downloaded and installed java 1.7, and changed my JAVA_HOME. I downloaded and unpacked Kepler and pointed it at my existing workspace.
I have two questions; First, when I click on "Window / Preferences", there is no entry for "Maven" on the left of the dialog. I shut down and rebooted the machine after I changed JAVA_HOME to ensure that didn't cause this.
I checked the list of installed plugins, and it lists m2e (v1.4).
Second, I am getting an error message "Plugin execution not covered by lifecycle configuration". There are a double-handful of sites indicating what to do about this, including the m2e's wiki pages, but over half the suggestions don't look reasonable, the wiki doesn't spell out what to do for its recommended solution, assuming you know, and the one that looked most promising to me involves using "Windows / Preferences / Maven".
So I'm most interested in the answer to the first question; if you have hints to offer on the second, I'm all ears...

Here are the things you can try:
Start Eclipse with the -clean switch
Uninstall / reinstall the plugin
Delete the plugin's files physically from the plugins folder and install it again from the Marketplace
If all else fails you can just get a fresh installation of Eclipse and reinstall your old plugins manually. There are some of them which won't work in a newer version of Eclipse (I remember for example that I had to install WindowBuilder all over again after an Eclipse version switch).

I believe this came about by installing a new version of eclipse but pointing it at a workspace for the previous version. I have been told that there is metadata attached to a workspace that has to do with plugins; this would be bound to cause problems for a version that didn't have the plugins. I eliminated the new install, installed it again, created a new workspace, and imported-with-copy the project I wanted, that has eliminated the error. I will pursue that further.
Thanks to Adam Arold who pointed out the metadata issue.

How to open a Apache Maven project on NetBeans 7.0.1

I'm trying to open a project created with Apache Maven in NetBeans, with no success. I followed the directions given by this link: http://wiki.netbeans.org/MavenBestPractices but the Open Project dialog does not recognizes the project in the folder. When I point to the folder that contains the pom.xml file, it shows as if the folder is empty, except for the sub-folders. Apparently Apache Maven is disabled, but I can't find how to enable it.
Could someone point what is the mistake that I'm doing?

please make sure the maven modules are actually installed in your distribution. (Tools/Plugins I believe). And the latest NetBeans version is 7.4, 7.0.1 is fairly old already.

I installed the NetBeans 7.4 from here: http://www.oracle.com/technetwork/java/javase/downloads/jdk-7-netbeans-download-432126.html and it worked! Probably the build from Ubuntu repositories has issues. Thanks for the suggestions!

Download and install JavaFX for Eclipse

I'm an experienced (Java, Eclipse & Maven) developer, and have used a couple of frameworks thus far. Every time I'm trying to start with something new, it seems like there are about a zillion configuration possible for downloading and installing it.
I've looked here for instructions, and all the near pages, but they seem out dated, the Eclipse plugin path is invalid, and when I install the latest version I've found no the site (2.0.2), it says that I have a newer version installed.
Also, the Maven setup in most posts I've read seems obscure.
I'm using:
Windows 7
Eclipse x64 Indigo
JDK x64 1.6.0.24
Maven 3.0.3
And I don't recall installing the JavaFX.
What an I missing? Where can I read about the setup in order to start working with this framework?

JavaFX gets installed if you install the latest JDK 7 from Oracle (co-bundled).
You can find the Eclipse plugin here:
http://efxclipse.org/
If your're interested in Maven builds: I've recently released an initial version of Drombler FX, a modular RCP for JavaFX based on OSGi and Maven (POM-first):
http://puces-blog.blogspot.ch/2012/12/drombler-fx-building-modular-javafx.html
http://wiki.drombler.org/GettingStarted

I did tried efxclipse but it was not enough for me. I have also tried to give the path of javafx jar file to efxclipse
Window->Prefrences->javafx->"The path to javafx jar which is
jfxrt.jar"
. But nothing worked for me I don't know what was going wrong.
Then I just add the jfxrt.jar file to my Library and everything worked fine :-
1. Right click your JRE System Library
2. Build Path
3. Configure Build Path
4. Add External Jars
5. "The path to jfxrt.jar"
You can download jfxrt.jar file from this link.
Or
If you have already downloaded the latest oracle JAVA JDK you will find in this path
Extracted_oracle_jdk_folder/jre/lib/ext/jfxrt.jar
That's it everything should work fine.

Try e(fx)clipse at http://efxclipse.org/. I'm a netbeans developer, but heard a lot of good stuff about that plugin from my eclipse using friends.

No Android project type in Eclipse->File->New-Project

I am running CentOS 5.5 x86_64 with JDK 1.6, Eclipse Galileo, and the 0.9.7 ADT is installed; however, after installation, the Android project type is not available. I have checked in the installed packages list and it is installed. Anybody encounter this problem before? Could it be due to my use of the 64-bit java VM that is installed on my system?

This usually happens when you dont select any android SDK in "Preferences > Android" You just have to reset the perspective in eclipse, Windows > Reset Perspective.
Hope this is still helpful.

Hope you have already set the Android Preferences if not Window -> Preferences-> Android and browse to the android SDK folder.
In rare cases even after doing this step, Android Project option doesn't show up in File -> New. But you can get it by File -> New -> Project .. and choose the android project from the options displayed.

Ok. I reinstalled eclipse and android. I think the problem was that I hadn't unpacked the android tools first. The plugin was installed, but it had nothing to talk to! Anyway, all the android related stuff now shows up in Eclipse.

Using Windows 7, 64-bit edition, with the latest Eclipse (Indigo) and the latest ADT plugin, I had the exact same problem. No Android project type, no Android in Windows/Preferences.
Like #Rubberman I solved the problem by totally re-installing Eclipse. Eclipse doesn't seem to use the standard Add/Remove Program stuff in Windows; I just deleted the Eclipse install directories and my Eclipse workspace directory, re-installed Eclipse, and re-installed the ADT plugin.
I would have liked to have just removed the plugin and re-installed without deleting the whole of my Eclipse install, but I couldn't figure out a way to do that. I don't see any way to remove a plugin, and when I tried to choose ADT for installation Eclipse gave me an error, saying "I can't install that because it is already installed."

I Know its a very old post..but still it may help someone with same problem...
I wanted to jst share that we can uninstall the plugins without the need of reinstalling eclipps..by simply going to 'already installed application' link and selecting all the android related options and simply clicking on uninstall button..Now you can add fresh android sdk to your ecllips..I have tried it and it works..
Hope, I helped aomeone..:-)

Ok, been looking for the answer to this for an hour, it's not well mentioned.
if you are using linux then you need to add 2 more things to install ADT correctly:
GEF from http://download.eclipse.org/tools/gef/updates/releases
WST Server Adapters from http://download.eclipse.org/releases/galileo/ (modify for your release)
do it the same as the adt plugin install.
maybe you need to uninstall then reinstall the adt plugin after?

You have to install the Eclipse plugin called ADT.
