Gradle 6.8 cannot run on JDK 17+, and Kotlin 1.5.31 is incompatible with Gradle 8.x, so `./gradlew test` failed with an incompatible task-action signature error on any modern JVM. JUnit 4.12 predates the fix for CVE-2020-15250. - Upgrade gradle wrapper to 8.11.1 - Upgrade Kotlin plugin to 2.0.21 and kotlin-stdlib - Upgrade JUnit to 4.13.2; kotlin-test-junit now pulls the right version - Switch from deprecated kotlinOptions.jvmTarget to jvmToolchain(21) - Replace deprecated mainClassName with application { mainClass = ... } - Remove the java plugin, redundant alongside the Kotlin JVM plugin - Remove JAVA_HOME and source-setup coupling from script/test and script/start Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
