+// This script adds support for the following two JVM system properties
+// that control the build for alternative JDKs (i.e., a JDK other than
+// the one used to launch the Gradle process).
+//
+// - customJavaHome: absolute path to the alternate JDK installation to
+//     use to compile Java code and execute tests. This system property
+//     is also used in spring-oxm.gradle to determine whether JiBX is
+//     supported.
+//
+// - customJavaSourceVersion: Java version supplied to the `--release`
+//     command line flag to control the Java source and target
+//     compatibility version. Supported versions include 9 or higher.
+//     Do not set this system property if Java 8 should be used.
+//
+// Examples:
+//
+// ./gradlew -DcustomJavaHome=/Library/Java/JavaVirtualMachines/jdk-14.jdk/Contents/Home test
+//
+// ./gradlew --no-build-cache -DcustomJavaHome=/Library/Java/JavaVirtualMachines/jdk-14.jdk/Contents/Home test
+//
+// ./gradlew -DcustomJavaHome=/Library/Java/JavaVirtualMachines/jdk-14.jdk/Contents/Home -DcustomJavaSourceVersion=14 test
