Access Transformers 1.7.10 ['SOLVED' i.e. used reflection instead]

[TheGreyGhost]

Hi

 

Could anyone point me towards a mod on GitHub or similar which uses Access Transformers? (private ->public for a field)

 

I've created an access transformer config file and it worked fine for the dev workspace but when I build to a jar and load it in a release environment, the field is still private.

 

I am about ready to explode trying to get them to work; I am using the FMLAT META-INF method, and FML is loading the rules ok but it just doesn't seem to apply them no matter what combinations I try. 

 

Based on the logs I know it's loading the three rules out of the access transformer file, and they are parsing correctly.  But it seems they are silently not applying.

 

Further information:

If I create a new Forge development environment, place my released mod into the eclipse/mods folder, then debug or run, it applies the access transformation no problem.  (It crashes soon after because all the names are obfuscated, but that's not the point...)

 

Some relevant error logs

 

 

the field I'm trying to modify in KeyBinding is keybindArray (field_74516_a)

@SideOnly(Side.CLIENT)
public class KeyBinding implements Comparable
{
    private static final List keybindArray = new ArrayList();
  ... snip ...

 

my access_transformer file, trying a few different rules

public net.minecraft.client.settings.KeyBinding * # All fields
public net.minecraft.client.settings.KeyBinding field_74516_a # srg name
public net.minecraft.client.settings.KeyBinding keybindArray # deobfs name

 

the error:

Battlegear2 uses access transformers, and I'm sure if you can catch GotoLink around he may answer any questions you have about it.

[TheGreyGhost]

Well I've spat the dummy and used Reflection get and set instead.  After a bit more testing I'm reasonably sure it's an FML bug related to (re)obfuscation, but maybe that's just sour grapes talking.

 

Anyway I don't need the access transformers any more.  If you know what went wrong, I'm interested to hear, but don't waste time trying to figure it out for my sake:)

From the new Forge RB changelog:

Fixed issue in loading non-coremod AccessTransformer files.

Graahrg  guess that will teach me to update Forge more often.

 

thanks
