I have installed Eclipse luna on my macbook(with Yosemite). Maven in eclipse works fine. Prior to that i installed maven in system (extracted downloaded package and set in the path). Both (Eclipse based and CLI based) maven works fine. Following are questions.
I suspect that, both maven tools use separate directories to store downloaded files. Which may eat up lot of space. Is it true?
Is there any way we can configure eclipse maven plugin to use maven installed by me or atleast use the same directory to save the space.
Will be thankful for any pointer.
Regards
I think the easiest way would be by using Homebrew. Do you have it installed?
Then you could do:
brew install maven
Then you can install the maven plugins on Eclipse, but I think Luna already comes with the bundle, si you just need to try.
Hope it helps!

our company uses the Eclipse IDE with some plugins that are required to start our platform. I want to create a bundle for our Java developers that contains the latest Eclipse Java (Oxygen) with the plugins already installed.
So far I've installed Eclipse with
sudo cask brew install eclipse-java
which created an /Application/Eclipse Java.app.
After installing the plugins within Eclipse with Help->Install New Software the ~/.eclipse/ was created in my home directory.
Is there some way to zip these folders to create an distributable package of eclipse or am I missing other files/directories?
Is it possible to move the plugins in the installation directory as well?
Thanks for your help!
It is not advisable to use any Eclipse distribution that's produced by packaging tools. It's best to download directly from eclipse.org, for various reasons.
As for customizing an Eclipse "package" for distribution yourself, have a look at the Oomph project, which is designed for that exact purpose (and others). Oomph is what produces both the installer and the downloadable packages of Eclipse IDE releases. You can read specifically about Oomph authoring here.
You can use the official eclipse installer. There is an advanced mode to disable the p2 pooling. Then using this mode, everything will go into the eclipse folder. Afterwards you can zip it and give it to others. Of course you are always bound to the CPU Arch still.
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).
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!
I am using eclipse juno version(RCP and RAP) in linux environment. Eclipse juno already has maven so, i think there is no need to install any m2e plugin. I want to use maven for Eclipse plug-in development. Please confirm me is it mandatory to install maven in this linux environment?
Short Answer
Yes
Long Answer
Yes, you will want to run it from the command line. You will want to be able to update to the latest version, which Eclipse isn't running. You will want to be able to point other applications like Jenkins at M2_HOME, lots of other reasons as well.
I downloaded eclim, and according to the installation guide
it requires Eclipse Helios 3.6.x.
So, I went and installed that version of Eclispe manually because it is not at Ubuntu's repositories.
What happened next was that, when I tried installing eclim, it said that it cannot recognize the eclipse version that I have.
Do you have any suggestions of how to resolve this issue?
The Eclipse that you install manually is not usually on the path that Eclipse is installed to when using the software center. I had this problem too while trying to install eclim.
There are two ways to fix it.
You can specify where the new Eclipse is installed to from your manual installation. For example, I manually installed Helios to $HOME/eclipse. When the installer gets to the point where it asks for eclipse's path, I specified it as /home/username/eclipse, replacing username with my name of course. That should find the helios installation, and not the installation in /usr/lib/eclipse.
The second way to do it is to manually make and install eclim from the repositories. The guide for this is here, http://eclim.org/guides/development.html#development-build. That will work you through building eclim from the development build, which may be better anyway as there may be new features not in the release version. Be sure to specify the eclipse home files in the Ant command, like so, ant -Declipse.home=/where/you/installed/eclipseto
Hope this helped, and merry days using eclim. It's really great.
