Run tests with JDK9 and version 2.14

Is it possible to run Tests with Java 9? We want check if our application is compatible with the coming Java 9. We does not need any Java 9 features. We have simple set the executable for the test task. We have try the current version 2.14 without any luck.

Good news, everyone.

We just released Gradle 3.0 M2 with initial Java 9 support.

Please give it a try and let us know if it’s not working for you.

Thanks for the hint. I have try it and post the first error with the jacoco plugin: Jacoco plugin does not work with Java 9
