| Compiling and testing against different JVMs |
| ============================================ |
| |
| By default tests are executed with the same Java Gradle is using internally. |
| |
| To run tests against a different Java version, define a property called |
| "runtime.java.home" or define an environment variable "RUNTIME_JAVA_HOME" |
| pointing at the JDK installation folder. |
| |
| If property is being used, it can be a system property (-D...) or a project |
| property (-P...). |
| |
| Example: |
| |
| gradlew test -p lucene/test-framework --tests TestJvmInfo -Dtests.verbose=true -Druntime.java.home=/jvms/jdk14 |
| |
| Note that an alternative JVM can also be made the "default" setting |
| by adding it to (project-local) gradle.properties. |
