[1.11.2] Wierd compilation error

[MisterPeModder]

Hello!

I currently working on a mod called TooManyOres mod that depends on a library mod called HexianCore.

The mod worked properly and i could compile it without any problem but recently, I encountered some pretty strange compilation error sthat only occurs when I'm trying to build the project (works fine in dev environnement).

It says that I didn't implemented the method GuiContainer::drawGuiContainerBackgroundLayer even though it is implemented the the GuiConainerBase class.

So I almost tried everthing and I could not find a solution to this problem, so if someone knows what i did wrong, I would be very grateful !

Could you post the compiler error log as well?

Edited September 22, 2017 by MDW01

[MisterPeModder]

It's in the "gradle log spoiler"

[MDW01]

Could you post a link to a repository with your code?

[MisterPeModder]

HexianCore: https://github.com/MisterPeModder44/HexianCore/tree/1.11.2/

It may take me a while to find out whats wrong. But in the mean time you could check when you last successfully compiled and what changes you have made since then that could be effecting this.

[MisterPeModder]

Hmm... the last time I compiled this mod I wasn't using hexian core as a dependency, what may have caused this issue is the fact that i moved most of the abstract classes/interfaces such as GuiContainerBase to my library.

[MDW01]

Have you added Hexian core as a dependency in gradle.

[MisterPeModder]

No but i added it as a jar file in the libs folder so it should work (I built my other mods this way so that is propably what's causing the problem)

[MDW01]

Yea with my core mod I usually don't start running into issues until I compile. So I would try adding it as a dependency in gradle.

[MisterPeModder]

Problem is: i dont't even know how Maven works so... I'm screwed 

[MDW01]

Neither do I but in the end it works and thats all that matters. Thankfully Forge has this nice article about it.

[MisterPeModder]

Well thanks i didn't knew about that! 

...But sadly this give me the exact same errors as previously.

[MDW01]

I can look at it more tomorrow. I tend to think better when I'm not half asleep.

1) Your reflection is broken you need to add the srg names as well. The findMethod you are using is deprecated and switching to the other one will make it compile. I believe that the problem is the null instance

2) All the other errors are that you are not implementing things in the classes. You need to implement the missing methods.

 

Once these things are fixed it compiles

1) oh I didn't know I had to include srg names!

2)well I know that, but the problem is that I DID implemented all of these methods
