Tutorial:Obtaining a crash report

This tutorial serves to help users on how to obtain crash reports generated by Minecraft. Crash reports can help developers confirm and diagnose issues and should be included in bugs on the bug tracker whenever possible.

Deobfuscating the crash report file with obfuscation maps and uploading the deobfuscated version to the Bug tracker may make it easier for Mojang Studios developers to track down the cause of the crash.

Retrace is the tool to parse obfuscation maps.[1] To run Retrace, you need to have Java 8 or above installed on your device.
