Eclipse安裝Maven套件時出現 "Cannot complete the install because one or more required items could not be found." 的解決方法

最近在Eclipse安裝Maven套件時，會出現這樣的錯誤

Cannot complete the install because one or more required items could not be found. Software being installed: Maven Integration for Eclipse (Required) 0.12.1.20110112-1712 (org.maven.ide.eclipse.feature.feature.group 0.12.1.20110112-1712) Missing requirement: Maven Integration for Eclipse (Editors) 0.12.1.20110112-1712 (org.maven.ide.eclipse.editor 0.12.1.20110112-1712) requires 'bundle org.eclipse.zest.core 0.0.0' but it could not be found Cannot satisfy dependency: From: Maven Integration for Eclipse (Required) 0.12.1.20110112-1712 (org.maven.ide.eclipse.feature.feature.group 0.12.1.20110112-1712) To: org.maven.ide.eclipse.editor [0.12.1.20110112-1712]

看起來是缺少一些dependency的套件， 查了一下，只要安裝GEF套件即可，網址在此：http://download.eclipse.org/tools/gef/updates/releases/
