Eclipse-Maven安装错误

我试图为Eclipse安装Maven插件，但我遇到了这个错误

我正在使用

面向Web开发人员的EclipseJavaEEIDE。 版本：靛蓝版 构建id:20110615-0604版本的Eclipse

Cannot complete the install because of a conflicting dependency.
  Software being installed: m2e - Maven Integration for Eclipse 1.0.100.20110804-1717 (org.eclipse.m2e.feature.feature.group 1.0.100.20110804-1717)

    This version of m2eclipse cannot be installed on top of the already installed m2eclipse. Uninstall the previous version of m2eclipse and try the install again. 1.0.100.20110804-1717 (org.maven.ide.eclipse 1.0.100.20110804-1717)

请参考下面给出的错误屏幕截图

您只需卸载m2eclipse版本0.12.x，然后重试安装。实际上，您正在尝试同时安装m2e和m2eclipse（阅读：旧版m2e）

我的Eclipse JDT和m2e版本是：

Eclipse Java Development Tools  3.7.0.v20110520-0800
m2e - Maven Integration for Eclipse 1.0.0.20110607-2117

我用的是Eclipse开普勒。在我的例子中，安装“Maven Integration for Eclipse（Juno和更新版本）”成功了。
