Error: Could not retrieve sbt 0.11.3 when running existing project in Play 2.1.0?

Question

I'm new to Play Framework. I've just read about how to create and run a play project. I've been given a project and am facing Error: Could not retrieve sbt 0.11.3:

Getting org.scala-sbt sbt 0.11.3 ...

Error: Could not retrieve sbt 0.11.3

I only installed Play Framework 2.1.0 distribution and nothing else.

How can I get passed the error and execute the play command successfully?

Solution 1

I think your existing project has dependencies to sbt 0.11.3 and you are running it with Play 2.1.0 which uses sbt 0.12.2.

Check the file build.properties located under the project folder. If it says 0.11.3 your project probably uses another Play version and need to be upgraded to 2.1.0.
The sbt-plugin should have Play 2.1.0 assigned - se plugins.sbt under project folder.

Either ugrade your project: http://www.playframework.com/documentation/2.1.0/Migration

Or - switch to an older Play version - the correct for your project. => http://www.playframework.com/download.

Solution 2

It seems you're using play 2.1.0 which is distributed with sbt 0.12.2.

The solution is not to upgrade your play distribution as you only need to edit your project/build.properties file and change

sbt.version=0.11.3

to

sbt.version=0.12.2

With the change, the project should be fine.
