Minecraft Forge Build Failed with an Exception: Troubleshooting and Reporting the Issue

When attempting to build a Minecraft Forge mod, you may encounter a frustrating issue where your build process fails with an exception. In this article, we'll dive into what causes such errors, how to troubleshoot them, and provide guidance on reporting the bug to the developers.

The Crash Outside the JVM in Native Code

One of the most common reasons for Minecraft Forge builds failing with an exception is a crash that occurs outside the Java Virtual Machine (JVM) in native code. This means that the error doesn't occur within the Java code itself, but rather in the native code that interacts with it.

Where to Report the Bug

To troubleshoot and report this issue, you'll need to identify the problematic frame where the bug occurred. The problematic frame will provide valuable information about what caused the crash, making it easier for developers to diagnose and fix the problem.

Enabling Minidumps on Client Versions of Windows

By default, minidumps are not enabled on client versions of Windows. To enable them, you'll need to follow a few additional steps. This is crucial as it allows you to provide detailed information about your build failure to the developers.

Java VM Information

When troubleshooting a Minecraft Forge build failure, it's essential to know the version of Java being used. In this case, the crash occurred on OpenJDK 64-Bit Server VM Microsoft-32931 (17.0.3+7-LTS, mixed mode, tiered, compressed oops, compressed class ptrs, g1 gc, windows-amd64).

A Fatal Error Detected by the Java Runtime Environment

The final message indicates that a fatal error has been detected by the Java Runtime Environment. This is typically followed by a detailed error message that provides further information about what went wrong.

In summary, when your Minecraft Forge build fails with an exception, it's essential to identify the problematic frame and enable minidumps on client versions of Windows. By providing detailed information about your build failure to the developers, you can help them diagnose and fix the issue more efficiently.
