      > The consumer was configured to find a library for use during runtime, compatible with Java 11, packaged as a jar, preferably optimized for standard JVMs, and its dependencies declared externally, as well as attribute 'org.gradle.native.operatingSystem' with value 'windows'. There are several available matching variants of org.lwjgl:lwjgl:3.2.3

The bytecode produced by the compiler also corresponds to the requested Java version, meaning that the compiled code cannot be executed on older JVMs.

The `release` option of the Java compiler was introduced in Java 9.
However, using this option with Gradle is only possible starting with Java 10, due to a https://bugs.openjdk.java.net/browse/JDK-8139607[bug in Java 9].
