Error: m2e Install In Eclipse

Question

I've been attempting to install Maven Integration for Eclipse and I've received these errors.

    Cannot complete the install because one or more required items could not be found.   Software being installed: m2e - slf4j over logback logging (Optional) 1.4.0.20130601-0317 (org.eclipse.m2e.logback.feature.feature.group 1.4.0.20130601-0317)   Missing requirement: Maven Integration for Eclipse 1.4.0.20130601-0317 (org.eclipse.m2e.core.ui 1.4.0.20130601-0317) requires 'bundle org.slf4j.api 1.6.2' but it could not be found   Cannot satisfy dependency:     From: m2e logback appender 1.4.0.20130601-0317 (org.eclipse.m2e.logback.appender 1.4.0.20130601-0317)     To: bundle org.eclipse.m2e.core.ui [1.4.0,1.5.0)   Cannot satisfy dependency:     From: m2e - slf4j over logback logging (Optional) 1.4.0.20130601-0317 (org.eclipse.m2e.logback.feature.feature.group 1.4.0.20130601-0317)     To: org.eclipse.m2e.logback.appender [1.4.0.20130601-0317] 

My process has been Help >> EclipseMarketplace >> Search "Maven Integration for Eclipse" >> Install (m2e)

Please help.

Edit

After running into a plethora of issues, the decision was made to uninstall Eclipse Indigo 3.6.2 and install Indigo 3.7 (as per the standards of the company I currently work at). After taking this course of action, all issues with installations (maven and otherwise) were resolved.

Answer 1

I ran into a similar issue today and found that this question also has recently been asked and answered at the atlassian forum as well. My solution was to install slf4j based on guidelines from this blog post about "SLF4J Logging in Eclipse Plugins".

To extract, here is what I did:

1. Eclipse -> Help -> Install New Software
2. Add a new software site:
   • Name: slf4j
   • Url: http://www.fuin.org/p2-repository/
3. Expand "Maven osgi-bundles" and select "slf4j-api"
4. Click "Next" and follow the installation.

After the installation has completed (and Eclipse has been restarted) I was then able to install the maven plugin.

UPDATE:

Some of the other answers in this thread now contain links to offical package repositories. I haven't tested if they are working, but if you would prefer to use an official repository, now you know where to find them :)
