jschnasse :
I have a Play 2.2.2 project I normally run with the activator 1.3.12. Now I updated to Java 11 and activator complains like:
The java installation you have is not up to date
activator requires at least version 1.6+, you have
version 11
Please go to http://www.java.com/getjava/ and download
a valid Java Runtime and install before running activator.
If I try to run the application with sbt 1.2.4 directly I get an unresolved dependency path error
Note: Unresolved dependencies path:
[warn] com.typesafe.play:sbt-plugin:2.2.2 (scalaVersion=2.12, sbtVersion=1.0) (/myProject/project/plugins.sbt#L8-9)
[warn] +- default:myProject-build:0.1.0-SNAPSHOT (scalaVersion=2.12, sbtVersion=1.0)
[error] sbt.librarymanagement.ResolveException: unresolved dependency: com.typesafe.play#sbt-plugin;2.2.2: not found
Does anyone have any advice on how to get this old project running under Java 11?
Luis Felipe Mendivelso Osorio :
In the case of SBT, remember that SBT is an open-source build tool for Scala and Java projects, similar to Java's Maven and Ant, in this order of ideas, Scala has a minimum and maximum requirement for compatibility with Java, in this link you can find the information:
https://docs.scala-lang.org/overviews/jdk-compatibility/overview.html
I should make a downgrade of your java version to 10.
Good luck.
