Re: [m2e-users] slf4j Dependency Error on plugin Install

Indigo is no longer officially supported for m2e, but we've created an update site that will allow the installation of m2e 1.4 into Indigo:

New to the group.  Hello!
Also – forgive me – little java experience and even less using Eclipse and maven.  That’s about to change.  I’m following company installation and configuration instructions to set up my environment with limited support from more colleagues unfortunately.
So, instructions called for installation of a specific combination that apparently worked together:
- Java 6 (jdk 1.6.0_33)
- Eclipse Indigo 3.7.0
- Maven 3.0.5
- “m2e – Maven Integration for Eclipse” plugin  (
But no one saved the binaries for Maven and the plugin and it doesn’t seem they are available anymore.
I have installed Maven 3.1.0 and am attempting to install the only available version of the maven plugin, 1.4.  The maven install seems to be okay:
c:\projects\Tools>mvn --version
Apache Maven 3.1.0 (893ca28a1da9d5f51ac03827af98bb730128f9f2; 2013-06-27 19:15:3
Maven home: C:\projects\Tools\apache-maven-3.1.0\bin\..
Java version: 1.6.0_33, vendor: Sun Microsystems Inc.
Java home: C:\projects\Tools\jdk1.6.0_33\jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"
When I try to install the m2e plugin, however, I get this (most recently):
Cannot complete the install because one or more required items could not be found.
  Software being installed: m2e - slf4j over logback logging (Optional) (
  Missing requirement: m2e logback configuration (org.eclipse.m2e.logback.configuration requires 'bundle org.slf4j.api 1.6.2' but it could not be found
  Cannot satisfy dependency:
    From: m2e - slf4j over logback logging (Optional) (
    To: org.eclipse.m2e.logback.configuration []
Sometimes in my trials and tribulations it said “editor” instead of “logback.configuration”.
Hoping one of you all can advise what I need to install where to get the plugin going.
- The maven has “slf4j-api-1.7.4.jar” and “slf4j-simple-1.7.4.jar” files in it already.  Don’t know how to get the plugin to “see” those. 
- I tried downloading the 1.6.2 verson of slf4j and tried copying the same two jar files from that version to the maven lib directory, but no diff. 
- There’s a “pom.xml” file in the slf4j zip file/structure, but I didn’t know where to copy it in the maven directory structure.  Can’t find any “pom.xml” file in maven directory structure itself.
Obviously I’m just trying things at random, which isn’t getting me anywhere.  Help?
Thank you!
More details:  (Note – I could paste the Eclipse configuration details, but seems like overkill.  Let me know if not)
- Windows 7 Enterprise, SP1  8GB, 64-bit O/S
- Eclipse Java EE IDE for Web Developers.
Version: Indigo Release
Build id: 20110615-0604
Eclipse Platform 3.7.0
- Eclipse, java, maven all installed into “c:\projects\Tools” directory.
- Eclipse launched via shortcut to a batch file thus:
set PATH=C:\projects\Tools\jdk1.6.0_33\bin;C:\projects\Tools\eclipse_Indigo\eclipse;C:\projects\Tools\apache-maven-3.1.0\bin;C:\projects\Tools\apache-ant-1.8.2\bin;%PATH%
set JAVA_HOME=C:\projects\Tools\jdk1.6.0_33
set ORACLE_HOME=C:\oracle\product\11.2.0\client_64
start eclipse
