Eclipse m2e插件似乎需要org.eclipse.jem.util 0.0.0

Question

我尝试使用帮助>安装新软件和更新站点安装Eclipse Juno的M2E插件http://download.eclipse.org/technology/m2e/releases.当我尝试安装'Maven Integration for Eclipse'时,我收到以下消息:

Cannot complete the install because one or more required items could not be found.
  Software being installed: m2e - Maven Integration for Eclipse 1.3.1.20130219-1424 (org.eclipse.m2e.feature.feature.group 1.3.1.20130219-1424)
  Missing requirement: m2e - Maven Integration for Eclipse 1.3.1.20130219-1424
  (org.eclipse.m2e.feature.feature.group 1.3.1.20130219-1424) requires
  'org.eclipse.jem.util 0.0.0' but it could not be found

如何避免此错误并安装M2E插件？

Answer 1

此问题是由我的Eclipse安装目录不可写引起的.这是一个全新的未配置的开箱即用安装,我已经/opt/eclipse在Linux 下安装了它.然而,Eclipse的预期写入 configuration和p2另外配置的安装目录的子目录,而且它不会给任何明显的错误,如果这些不可写.

您可以通过确保用户可以写入Eclipse的安装目录来避免此错误.
