Research direction

Reproduce the failure with the linked MultiLoader template by running the Forge module's build and inspecting the reobfJar task. Start with net.minecraftforge.gradle.userdev.tasks.RenameJarInPlace.java and the srgutils loading calls shown in the stack trace. Done means the template build completes without the IndexOutOfBoundsException.

Description

FG6

When using this multiloader template, ForgeGradle is running into an odd exception in reobfJar during build. I've tried experimenting with removing certain parts of the template, but couldn't pinpoint what exactly is causing the issue.

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':forge:reobfJar'.
