|
// 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
