I use Gradle to configure Eclipse.
For JDK11 to be used as if it were JDK8 in Eclipse I have added:
sourceCompatibility = JavaVersion.VERSION_1_8
targetCompatibility = JavaVersion.VERSION_1_8
if (JavaVersion.current() > JavaVersion.VERSION_1_8) {
tasks.withType(JavaCompile) {
options.compilerArgs.addAll(["--release", "8"])
}
}
