Forge reobfuscation randomly fails on rock/stone

[Two]

Whenever I have a block in my mod that uses Blocks.stone or Materials.rock reobfuscation completely randomly fails sometimes.

 

That is: the code works, then (without any change) I do a re-compile, and the game crashes with

Then I recompile the exact same code-base (without any changes) and the crash is gone. I have not seen this happen with anything but Materials.rock / Blocks.stone.

 

This is really annoying when you do a quick recompile to change something like version number after extensive testing, upload the mod just to realize that it is crashing because of this.

How do you build your mod? You have to use

gradlew build

.

I am not sure if there is even any other way.

 

So yes: I am using the standard gradle tasks like clean and build.

I am not sure if there is even any other way.

Some people just export it from Eclipse and expect it to work.

 

I don't know what could cause the issue. We (I) need to have more info:

1. The Forge version you are using

Caused by: java.lang.NoSuchFieldError: rock
at two.graves.blocks.BlockGrave.<init>(BlockGrave.java:40)

2. Show us line 40 from BlockGrave. Or do you have a GitHub workspace we can use?

I had this issue starting with at least Forge version 1277 and I still have the issue with 1481.

 

You can find my mods here: https://github.com/twothe/

 

Affected are all mods that somehow use stone/rock as written above. I could not yet find any pattern to this, it seems to happen just randomly and does not seem to be associated to my code.

The error occurred again yesterday, and I can now say for sure that it is a re-obfuscation failure.

 

I had just finished an update, did clean & build, tested the result in the IDE (non-obfuscated) and everything was working fine. So I copied the lib from that build to a real MC environment and it failed with the rock issue. I hit clean & build again, copied the lib again and then everything was working fine.
