+// 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

-/**
- * Apply the JVM Toolchain conventions
- * See https://docs.gradle.org/current/userguide/toolchains.html
- *
- * One can choose the toolchain to use for compiling the MAIN sources and/or compiling
- * and running the TEST sources. These options apply to Java, Kotlin and Groovy sources
- * when available.
- * {@code "./gradlew check -PmainToolchain=8 -PtestToolchain=11"} will use:
- * <ul>
- *     <li>a JDK8 toolchain for compiling the main SourceSet
- *     <li>a JDK11 toolchain for compiling and running the test SourceSet
- * </ul>
- *
- * By default, the build will fall back to using the current JDK and 1.8 language level for all sourceSets.
- *
- * Gradle will automatically detect JDK distributions in well-known locations.
- * The following command will list the detected JDKs on the host.
- * {@code
- * $ ./gradlew -q javaToolchains
- * }
- *
- * We can also configure ENV variables and let Gradle know about them:
- * {@code
- * $ echo JDK11
- * /opt/openjdk/java11
- * $ echo JDK15
- * /opt/openjdk/java15
- * $ ./gradlew -Porg.gradle.java.installations.fromEnv=JDK11,JDK15 check

-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
