我看到下载 Play 2.4.x 和 Play 2.3.x 的相同链接

Question

I am trying to learn Play Framework to start using this in my existing project which is targeted for Java 7 alone. So, I try to download old version 2.3.9 which supports Java 6+. But in site I see same activator url to download old versions as well. How could activator know that I am planning to use Play 2.3.9 version. I am getting Unsupported major.minor version 52.0 when I try to run sample application

Answer 1

Play version is set in the plugins.sbt file :

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % playVersion) 

If you want to use Play 2.3.9, you should use:

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.9")
