Xeres uses JDK 21. It has been tested with Temurin and GraalVM. Do not use Zulu because its integrated JavaFX has compatibility problems.

Updating Java version

First, consider sticking to LTS unless there's a very desired feature or an important bug fix. There's often a gap between no support of a non-LTS version and Gradle not supporting the newer one yet.

  • make sure there's a Temurin release (https://adoptium.net/temurin/releases/)
  • make sure IntelliJ supports it (https://www.jetbrains.com/help/idea/supported-java-versions.html although this page is often wrong)
  • make sure Gradle supports it (without using toolchains)
  • download the latest Temurin release in IntelliJ
  • switch the project SDK to it
  • change the sourceCompatibility in the root build.gradle
  • run all tests and make a dry run
  • change the java version in .github/workflows
  • change the java references in the root README
