我正在尝试在Eclipse Luna中安装Glassfish工具,但是一直收到以下错误信息:
Cannot complete the install because one or more required items could not be found.
Software being installed: GlassFish Tools 7.3.3.201412231459 (oracle.eclipse.tools.glassfish.feature.group 7.3.3.201412231459)
Missing requirement: GlassFish Tools 7.3.3.201412231459 (oracle.eclipse.tools.glassfish.feature.group 7.3.3.201412231459) requires 'org.eclipse.sapphire.feature.group [8.1.0,8.2.0)' but it could not be found
我该怎么办?谢谢。
