Missing metadata

[ZappSnapp]

I'm new to modding.

I'm trying to add a block to Minecraft. I managed to add a very simple (default purple/black) block with no assets and everything went well, I had a block and an associated item. 
 

I've added an assets folder in my src directory and added some color and model data to my block&item.. However I came accross this error when I tried running Minecraft again

Any help appreciated,
Thank you

I'm new to modding as well and I don't understand what this message means. I'm getting the same error under the same conditions. What am I supposed to do?

Edit src/main/resources/META-INF/mods.toml so that it contains the information Forge needs.

What exactly am I supposed to put into the .toml? Here is the file for reference

Also, one thing doesn't look like another. I.e. compare the screenshot you shared with the toml file contents.

I am new to modding and Java and I had this same problem.

 

In my mods.toml file I have this line: 

modId="fdmapexplorer" #mandatory

FDMapExplorer is the name of my mod.

 

I found this in my main mod java file:

@Mod("assets/fdmapexplorer")

I know I didn't type that in so at some point my IDE(IntelliJ IDEA) may have tried to help. Anyway...

 

I changed it to:

@Mod("fdmapexplorer")

AND TA-DA! Everything works!

Hopefully this helps you.

Thank you for the one actually helpful reply in this thread. I think the problem is that if you moved/renamed the mod_id directory, it replaced all instances of your mod_id in your code with 'assets/mod_id'

Provide a possible reason why IntelliJ is being stupid
