Use the marketplace in eclipse indigo to install Maven Integration for eclipse. But when confirming selected features, no matter I choose "Maven Integration for eclipse" only or with "slf4j over logback logging",the error remains :Cannot complete the provisioning operation. Please change your selection and try again. See below for details.
Cannot complete the install because one or more required items could not be found.
Software being installed: m2e - Maven Integration for Eclipse 1.4.0.20130601-0317 (org.eclipse.m2e.feature.feature.group 1.4.0.20130601-0317)
Missing requirement: async-http-client 1.6.5.20130531-2315 (com.ning.async-http-client 1.6.5.20130531-2315) requires 'package org.slf4j 1.6.2' but it could not be found
Cannot satisfy dependency:
From: m2e - Maven Integration for Eclipse 1.4.0.20130601-0317 (org.eclipse.m2e.feature.feature.group 1.4.0.20130601-0317)
To: com.ning.async-http-client [1.6.5.20130531-2315]
A similar bug report has been delivered here http://marketplace.eclipse.org/content/error/report/955795, remain unread, is it a bug of eclipse marketplace, or how can I solve this problem?
回答1:
Indigo is almost 3 years old and 3 major releases behind. Can you update to the latest Eclipse instead?
If not, then try installing via Help > Install New Software....
In the Install dialog, select the Indigo update site in the Work with drop-down. Let it load the list and then in the search field type "maven" and select the m2e feature.

Here is a link to the answer, https://stackoverflow.com/a/4297912 also, when it pulls up result, type in "m2" in the search box. and that should pull up the maven plugin for eclipse
回答3:
go to this link download the file below this line (Install Eclipse plugins Automatically, if you have a clean install of 3.7 (Indigo) ) and extract the file in eclipse folder restart it and try install from marketplace

You can try install Maven Integration from another way, not from Market Place.
Here another plugin, called Eclipse IAM, that contains Maven Integration and the instructions for the installation
Eclipse IAM
I hope this help you!
回答5:
Since Eclipse 3.7 (Indigo), m2e is now hosted at eclipse.org. To install it, you just need to use the default Eclipse update site:
http://download.eclipse.org/releases/kepler
http://download.eclipse.org/releases/juno
http://download.eclipse.org/releases/indigo
etc.
