If you working with IntelliJ IDEA you may notice, that changing Project’s JDK version is not affected to Gradle build/run.
To force Gradle to use a specific JDK version / vendor you merely need to change Gradle JVM version in IntelliJ IDEA settings:
Settings → Build, Execution, Deployment → Build Tools → Gradle → Gradle JVM.
