This is what I was getting when tried to install m2e from Eclipse Market place. I am using Eclipse Juno.
Cannot complete the install because one or more required items could not be found. Software being installed: m2e - Maven Integration for Eclipse (includes Incubating components) 1.5.0.20140606-0033 (org.eclipse.m2e.feature.feature.group 1.5.0.20140606-0033) Missing requirement: Maven Integration for Eclipse 1.5.0.20140606-0033 (org.eclipse.m2e.core 1.5.0.20140606-0033) requires 'bundle com.google.guava [14.0.1,16.0.0)' but it could not be found Cannot satisfy dependency: From: m2e - Maven Integration for Eclipse (includes Incubating components) 1.5.0.20140606-0033 (org.eclipse.m2e.feature.feature.group 1.5.0.20140606-0033) To: org.eclipse.m2e.core [1.5.0.20140606-0033]
However, the below links is perfect, it works for me.
