The project updates its configured SBT version from 1.12.15 to 2.0.6.

Changes

Build Tooling

Layer / File(s)	Summary
SBT version update project/build.properties	The configured SBT version changes from 1.12.15 to 2.0.6.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Mergeability Score: 🟡 Moderate · up to 47b43

This update requires JDK 17 or newer, while CI still needs its Java version updated from JDK 11; merge should wait for that configuration change or explicit owner acceptance. Configured sbt plugins should also be verified for sbt 2.x compatibility.

sbt 2.0.6 Java 17 minimum requirement official documentation

💡 Result:

The minimum Java (JDK) requirement for sbt 2.x, including version 2.0.6, is JDK 17 or higher [1][2][3]. Official documentation and release specifications explicitly state that sbt 2.x requires at least JDK 17 to run [1][4]. The build tools include built-in version checks that fail early if a version lower than JDK 17 is detected when attempting to run sbt 2.x [5][3]. This requirement was established in coordination with the broader Scala 3 ecosystem, which also requires a minimum of JDK 17 for versions used by sbt 2.x metabuilds [6][2].
