activator eclipse command shows sbt.ResolveException

I have created a new project by using activator new simple play-scala command.simple is my project name.I would like to import this project into my eclipse(ScalaIDE),so I used activator eclipse command but It showed the below Exception

[error] Not a valid command: eclipse (similar: help, alias)
 [error] Not a valid project ID: eclipse 
[error] Expected ':' [error] Not a valid key: eclipse (similar: deliver, licenses, clean) 
[error] eclipse [error]

for this error I added addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "4.0.0") https://www.playframework.com/documentation/2.4.x/IDE command in simple/project/plugins.sbt It resolved the above mentioned error but It shows the error
