将Play的2.2源代码附加到应用程序

使用Play 2.1.3,我可以使用附加Play的源代码$ play eclipse with-source=true.但是现在,在迁移到Play 2.2.1之后,当我尝试运行该命令时,我得到以下错误.

$ play eclipse with-source=true
[info] Loading project definition from C:\Play\dcid\project
[info] Set current project to dcid (in build file:/C:/Play/dcid/)
[info] About to create Eclipse project files for your project(s).
[info] Successfully created Eclipse project files for project(s):
[error] Expected ID character
[error] Not a valid command: with-source
[error] Expected project ID

[error] Expected key
[error] Not a valid key: with-source (similar: watch-sources, watchSources, sources)
[error] with-source=true
[error]            ^

命令的语法是否已更新？我怎么能克服这个？
