Mod works in eclipse but not in Minecraft

[Geometrically]

I have coded my mod in eclipse and when I run it it is perfectly fine. When I put it into the mods folder and run Minecraft Forge, it comes up with this:

how r u exporting?

[TmzOS]

Did you used the defined methods to generate the *.jar file?

 

See this if not: http://www.minecraftforge.net/forum/index.php/topic,14048.0.html

[Geometrically]

I used gradlew build to get my mod's jar file which I used to put in the mods folder.

[jeffryfisher]

Did you put your mod's info into the build.gradle file?

 

In particular, you need to edit three lines:

 

version = "mcVersion-modVersion"      // Follow pattern <mcVersion>-<modVersion>
group= "net.domain.mod"              // Inverted domain (jeffryfisher.net) dot package (always all lower-case)
archivesBaseName = "modname"        // modid = package name  (always all lower-case)

Actually it is probably in your mcmod.info.

Okay. In eclipse, I put my mcmod.info file in the resources folder. Is that the wrong place? The text in my mcmod.info file is this.

It still won't work. It doesn't seem to find my mcmod.info file.
