My mod is using textures from modfolder/bin/assets/modid/textures/items rather than modfolder/src/resources/assets/modid/textures/items. They usually sync together or one copies from another but that's not happening. What am I doing wrong?

Did you just upgrade to IntelliJ 14?

 

If so read this

If you are using Intellij 14 (which you should) you need to add the following to the end of your build.gradle before importing:

sourceSets { main { output.resourcesDir = output.classesDir } }

If you don't do that, your assets will not work. (Thanks to Cazzar for this solution)

I don't even know what IntelliJ is , much less if I'm using it or not

OK, you're probably not then

 

IntelliJ IDEA is an alternative to Eclipse.

 

If you're using Eclipse I have no idea what's going wrong, sorry
