Scala IDE requires JDK 8, it doesn't work with JDK 9 yet: http://scala-ide.org/download/sdk.html (in the "Requirements" section, it states "JDK 8").

I can recommend using IntelliJ with the Scala plugin instead - even the community version is much better than any Eclipse-based IDE, including Scala IDE: https://www.jetbrains.com/idea/download/

That said, work is still ongoing on full JDK 9+ support in Scala: https://github.com/scala/scala-dev/issues/139. This mainly pertains to building the Scala compiler itself, though; more than likely, you can compile your Scala code using JDK 11 without problems.

An official webpage with the latest status of Java version compatibility, including links to the relevant GitHub issues, is available here: https://docs.scala-lang.org/overviews/jdk-compatibility/overview.html
