Hello, I recently tried to open MCreator, so there was a problem that is this:
Executing Gradle task: setupDecompWorkspace --refresh-dependencies
Build info: MCreator 2020.2.14217, 1.12.2, 32-bit, 3071 MB, Windows 7, JVM 1.8.0_232, JAVA_HOME: C:\Program Files\Pylo\MCreator\jdk
Download http://files.minecraftforge.net/maven/net/minecraftforge/gradle/ForgeGr…
This mapping 'snapshot_20171003' was designed for MC 1.12! Use at your own peril.
