Expected Behavior

Gradle works on JDK 14

Current Behavior

Gradle does not work on JDK 14

Context

I tried to upgrade a Gradle project to JDK 14.

Steps to Reproduce

Create a simple Gradle project by creating the following build.gradle file:

plugins {
    id 'java'
}

group 'some.group'
version '0.0.1-SNAPSHOT'

sourceCompatibility = 14

repositories {
    mavenCentral()
}

Run it using gradle --scan or something like that.

Your Environment

The following file stderr.txt was produced by, using the following build.gradle.txt as build.gradle:

./gradlew --stacktrace --info --debug >stderr.txt 2>&1

build.gradle.txt

Closing this issue. I've just tried Gradle 6.3-rc-4 and it works just fine with JDK 14.

Same issue with openjdk version "14.0.1" 2020-04-14, brand new installation, on Windows.
Fixed by editing gradle-wrapper.properties to download the 6.3 version as suggested in https://stackoverflow.com/questions/35000729/android-studio-could-not-initialize-class-org-codehaus-groovy-runtime-invokerhel

I took advice of christianhujer and downloaded gradle 6.3 and java jdk 14. Downloaded them from here: https://jdk.java.net/archive/ and https://gradle.org/releases/ I was then able to run gradle wrapper with no issues. Thanks for your assistance christianhujer. Cheers!
