Gradle: Could not determine java version from '12.0.2'

[Sweddy]

Expected Behavior

I am attempting to run the command gradlew setupDecompWorkspace in the command prompt. I expect it to be run fully and properly.

Current Behavior

When I run gradlew setupDecompWorkspace the build immediately fails and the issue is stated as being the one in the title, Could not determine java version from '12.0.2'.

Context

As stated above, I am attempting to run the command gradlew setupDecompWorkspace in the command prompt, but it fails with the stated exception whenever I do. I have updated Gradle to the version 5.1.1 and have likewise updated the Gradle Wrapper using the command gradle wrapper --gradle-version 5.1.1 in the command prompt, and yet the build still fails. How do I best go about fixing or circumventing this problem?
