Thank you! I tried using 1.8 now. I ran the same command and now it fails with following exception: Could not determine java version from '11.0.1'.
I'm new to mod development and this is my first attempt. I am new so I followed along the "Getting Started" guide on the forge documentation. I downloaded the mdk zip and copied "build.gradle", "gradlew", "gradle/" and "gradle.properties" to a new folder. I opened a shell and ran ./gradlew setupDecompWorkspace It failed with following exception: Task 'setupDecompWorkspace' not found in root project 'testmod'. I am on mac and using IntelliJ IDEA
