MISSING REPLACEMENT DATA FOR SRG_DIR when building my project

Plugins Plugin Development

I have the following build.gradle: build.gradle · GitHub
When I try to build it, I get a MISSING REPLACEMENT DATA FOR MAPPING_CHANNEL gradle error. Is there something I’m missing?

You need to pass a mappings field to the minecraft block, like this

mappings = "snapshot_20160822"

Mappings exports that you can use can be found here, just get rid of the mcp_ prefix, and replace the - between either snapshot or stable, and the number, with an underscore

i.e. mcp_snapshot-20170716-1.12 becomes snapshot_20170716

Thanks!
Now, I’m getting a new error:


* What went wrong:
Could not determine the dependencies of task ':copySrgs'.
