有人能够在 Eclipse 3.6.2 上成功安装 Papyrus 吗？
I have just downloaded the latest Eclipse Java EE Helios 3.6.2. When I attempt to install Papyrus using the Eclipse Marketplace through Yoxos, I get the following dependency error:

Has anyone been able to install Papyrus on Eclipse 3.6.2 successfully?

使用：Papyrus 构建站点
并确保您的可用站点包含 helios 来解决所有缺失的需求
Use: Papyrus Build Site
and make sure that your available sites include helios to resolve all missing requirements
该错误表明您尝试安装的 Papyrus 插件需要 Eclipse Galileo（EMF 2.5，而不是 EMF 2.6）。您需要返回到较旧的 Eclipse 版本，或者向 Papyrus 插件的提供商询问有关 Helios 支持的信息。
That error indicates that the Papyrus plugin you are trying to install requires Eclipse Galileo (EMF 2.5 as opposed to EMF 2.6). You will either need to go back to the older Eclipse release or inquire with the providers of Papyrus plugin about Helios support.
Papyrus 有两个版本可用：一种来自 www.papyrusuml.org，仅支持 Eclipse 3.5 及之前版本，另一种来自 http://www.eclipse.org/modeling/mdt/papyrus/。后者支持 3.6 及更高版本。
根据错误消息，Yoxos 站点的版本是旧版本（它使用 com.cea.papyrus 包名称而不是 org.eclipse 包名称。
There are two versions of Papyrus available: one from www.papyrusuml.org that is supports only Eclipse 3.5 and before, and a newer one from http://www.eclipse.org/modeling/mdt/papyrus/. The latter one supports 3.6 and newer.
According to the error message, the version from the Yoxos site is the older one (it uses the com.cea.papyrus package names instead of the org.eclipse ones.
