The current LTS versions are normally tested in our CI matrix and by the Scala community build. Scala provides experimental support for running the Scala compiler on non-LTS versions of the JDK. These versions will remain supported (by Oracle, and likely by the rest of the ecosystem, including Scala) for longer than the versions in between. (For this reason, some Scala developers use a newer JDK for their daily work but do release builds on JDK 8.) Long Term Support (LTS) versionsĪfter Java 8, Oracle introduced the concept of LTS versions of the JDK. If you compile on JDK 11+ but want to allow your users to stay on 8, additional care is needed to avoid using APIs and features that don’t exist in 8. JDK 8 remains in use at some shops (as of 2023), but usage is declining and some projects are dropping support. Since the JVM is normally backwards compatible, it is usually safe to use a newer JVM for running your code than the one it was compiled on, especially if you are not using JVM features designated “experimental” or “unsafe”. JDK 8, 11, 17, and 21 are all reasonable choices both for compiling and running Scala code. Requests adding additional columns to this table. Using a different build tool, such as Gradle or Maven? We invite pull The linked page includes contact information for inquiring about supported and recommended versions. Lightbend offers commercial support for Scala 2. Using latest patch version of Scala is always recommended. * = forthcoming support available in nightly buildsĮven when a version combination isn’t listed as supported, most features might still work. Sometimes new JVM and JDK (Java Development Kit) versions require us to update Scala to remain compatible. (Other supported platforms: Scala.js, Scala Native.) Scala’s primary platform is the Java Virtual Machine (JVM).

Alternatively, you can click the Start button and enter "Terminal" in the search bar. Hit Windows+X to open the Power User Menu, then tap "i" to open up Terminal. It doesn't matter if you use Command Prompt or PowerShell. The best way to determine which version of Java your PC is using is via the Terminal. Related: 7 Ways to Open Windows Terminal on Windows 11 That isn't usually a problem - you just need to be aware of which version you're actually using. The discrepancy occurs because multiple versions of Java are installed simultaneously. But that doesn't always display the version your system will actually try to use if you run a JAR file. For example, you can usually enter "About Java" in the Start Menu search and click the result to get a Java version. There are plenty of ways to determine what version of Java you have installed, whether you're using Windows 11 or Windows 10. Check Your Java Version with the Terminal How do you know which version you're using? Luckily, one command is all you need. The problem gets worse if you've installed multiple versions of Java. Occasionally programs will recommend or require a specific version of Java to function.
