When importing a maven project into Eclipse (after installing the maven plugin) I get the following errors:
UNKNOWN HOST: http://releases.liferay.com/tools/ide/latest/stable/compositeContent.xml
softlayer-ams.dl.sourceforge.net
Error installing m2e connector for liferay-maven-plugin contacting repository http://releases.liferay.com/tools/ide/latest/stable/
Should I install Liferay IDE? liferay - http://releases.liferay.com/tools/ide/latest/milestone/
Any ideas?
I installed liferay plugin now I get
Cannot complete the install because of a conflicting dependency.
m2e connector for jaxb2 3.0.0.20130330-0126
m2e connector for mavenarchiver pom properties 0.16.0.201401211452
m2e-liferay - Maven Integration for Liferay IDE 2.0.1.201401270944-ga2
I was able to import the project but now it says:
The container 'Maven Dependencies' references non existing library jnlp-1.6.jar
Solved: Uninstall Eclipse. Then re-install with the needed plugins.
I solved the problem installing "Maven Integration for WTP"
For Eclipse Kepler you can find it here:
http://download.eclipse.org/releases/kepler
m2e-wtp - Maven Integration for WTP (version 1.0.1)
It's inside "Web, XML, Java EE and OSGi..."
This package includes "m2e - Maven Integration for Eclipse" and my problem before was I used to install only this one

In order to solve the following Maven pom.xml import error:
Plugin execution not covered by lifecycle configuration: org.codehaus.gmaven:groovy-maven-plugin:2.0:execute ... Maven Project Build Lifecycle Mapping Problem
I'm trying to install https://github.com/groovy/groovy-eclipse Groovy-Eclipse
plugin.
When I do this I see the following solution at Eclipse install window:
Groovy-Eclipse won't work with m2e plugin for a some reason.
What can be a reason of this and how to fix this ?
The Groovy-Eclipse M2E integration feature includes the Eclipse m2e feature. If you complete the installation, you should see the Maven integration feature nested under Groovy-Eclipse M2E in the Installation Details dialog.

This is while importing maven's poms directly. Whats the impact if not installed?
2) Is system admin access required on the box to uninstall 'default'plugins and softwares in eclipse juno?
Removed this eclipse plugin and I am able to import the project's poms as well.
(one of the classic cases compatibility of different plugin's version on the IDE)

Getting the above mentioned error when installing M2E in Eclipse. The M2E URL that I used is
http://download.eclipse.org/technology/m2e/releases
As of late 2011, the M2Eclipse project was donated to the Eclipse foundation by Sonatype and is now called simply M2E. As of the Indigo JEE SR2 release, this plugin can be found in the pre-configured "Indigo" update site contained inside Eclipse, so you don't have to add any new update site.
To install, do the following:
Launch Eclipse; select the Help->Install New Software menu item.
Select the "Indigo" update site and wait for the software choices to
pop up in the table in the lower portion of this "Install" dialog (it
can take up to a minute).
In the table, select "General Purpose
Tools" and then "M2E - Maven Integration for Eclipse", click Next and
finish the installation of the plugin.
Restart Eclipse as directed.
Sometimes, for older Eclipse, like Helios, version 1.5 or 1.4 throws similar error. You can try with 1.3 in that case :
http://download.eclipse.org/technology/m2e/releases/1.3

Error: m2e Install In Eclipse
(11 answers)
Closed 8 years ago.
I'm working on Eclipse 3.7 (indigo) on Ubuntu 12.04 LTS, and I am trying to install the Maven plugin.
Following this page, I added http://download.eclipse.org/technology/m2e/releases to the Eclipse Install new software prompt box. It recognised the URL and showed "Maven Integration for Eclipse"
But when I click on Next, it gives this error.
Cannot complete the install because one or more required items could not be found.

What should I do? Please help.
Use the following URL in the "Install New Software" as a repository instead: http://download.eclipse.org/technology/m2e/releases/1.3.
I tried it and it works, no more errors.
this is the big problem of eclipse because mostly eclipse support other Maven
this is plugins for eclipse heilios only
http://download.eclipse.org/technology/m2e/releases/1.3
In Eclipse market place use this URL:-
http://download.eclipse.org/technology/m2e/releases/1.3/
It will install the maven plugin on eclipse successfully without any error.
It seems like somehow it is not able to download the slf4j related artifacts , for now you can unselect the checkbox while installing maven plugin .
Please see the attached image.
If it also don't work then manually download the plugin and drop it in eclipse plugins folder.
My eclipse version is indigo.
I install maven plugin from eclipse install/update:
help ---> install new software --->add,
URL: http://download.eclipse.org/technology/m2e/releases

I don't know what's "org.eclipse.platform.feature.group 3.6.0", I tried to search for install it but I can't.
Wish your response. thx.
Why not to use Eclipse Marketplace? Help -> Eclipse Marketplace... and then install Maven Integration for Eclipse and optionally Maven Integration for Eclipse WTP. It works for me.
Please try to use this URL instead of yours: http://m2eclipse.sonatype.org/sites/m2e/
