Help with Gradle

Hi there!

I’m new to coding. I have been attempting to follow the instructions for the program described here

Whenever I run the “./gradlew assemble” command (see the README.txt file in the above link for more details), I get the following error: FAILURE: Build failed with an exception. * What went wrong: Could not determine java version from ‘11.0.3’

Does anyone know how to solve this problem? Simple explanations are appreciated!

The version of Java you’re using is too new for what is supported by what’s in the rpi-ws281x-java project. You’d probably be best off using Java 8 instead of Java 11 for this.
